Advanced Search

The Advanced Search allows the user to search in specific fields* of the catalogue record in addition to an All Fields search. As well as being able to search on multiple terms in one box, as in the basic search, the user can also combine search terms entered in different boxes with the use of the Boolean operators AND NOT OR. This means a search can be built up to include certain criteria and exclude others.

*The fields in the catalogue record that searches are performed on are:
  • All Fields - searches on all of the catalogue record except for the access conditions and variables
  • Title - searches on all areas of title - main, sub-title, alternative, series
  • Subject - searches on keywords, subject category, abstract and main topics
  • Keyword – performs a free-text search only on HASSET subject keywords list
  • Geography – searches on geographic coverage (country, region, county/district, city/town, village etc.) as well as 'location of units of observation' i.e. National, Subnational or Cross-national
  • Data Creator/Funder - searches on names and affiliations for Depositor, Principal Investigator, Data Collector, Original Data Producer, Funder
  • Methodology – searches on Time Dimensions, Sampling Procedures, Method of Data Collection
  • Publications – searches on publications and reports resulting from primary and secondary analysis
  • UKDA Study Number – searches on study numbers

Multiple search terms can be entered within one field and combined by checking the Any All Exact buttons (the default is All). For example the words health care are entered with the:

  • Any button checked, the search will retrieve datasets which have any of the words (health or care) somewhere in the field being searched on
  • All button checked, the search will retrieve datasets which have all words (health and care) somewhere in the field being searched on
  • Exact button checked, the search will retrieve datasets which have the exact phrase (health care) somewhere in the field being searched on

Exact phrase search - Basic Search

Put double quotation marks around words to search for an exact phrase. For example, "family history" will look for the complete phrase family history. This search will be performed on all areas of the catalogue record (excluding the publications).

Note: Enclosing the search string in quotes will result in a slower search response.
Truncation search/wild cards - Basic and Advanced search

Use * to look for words with the same stem. For example, type child* to find child, children, childbirth, child-care, childminding and so on. A search on child (without *) will only retrieve records containing the actual word child.

(Basic Search only) A search on *crim* will retrieve crime, criminal, discrimination, crime-related etc.

A question mark ? is used to substitute a single letter, for example wom?n will retrieve either woman or women.

Note: Sort by date does not work for truncated and wild card searches in the Basic Search.

Name search - Basic Search
  • Searching on a personal name:
    To search for an individual's name (e.g. depositor) in the Basic Search it is advisable to enter the surname only.
  • Searching for an organisation:
    Names of organisations are usually entered in the catalogue record in full e.g. Economic and Social Research Council rather than as an acronym e.g. ESRC. It is therefore advisable to search for both the full name and the abbreviation.

Name searches in the Basic Search will retrieve records which contain that name anywhere in the record. For a more precise search it is advisable to use the Advanced Search where a more focused search can be performed on the Data Creator/Funder field.

See Data Creator/Funder for more help on name searching.
Results - Basic Search

There is no maximum limit to the number of hits retrieved. The hit number is displayed at the top of the list.

The default is for retrieved studies to be ordered by relevance. This order can be changed by clicking on Sort by date where results will be ordered by date of data coverage with the most recent first. Where the list contains several datasets with the same temporal coverage these will be displayed in study number order.

Note: Sort by date does not work for truncated and wild card searches. Relevance

The Data Catalogue currently uses Zoom in the search engine for the Basic Search. The results are sorted in order of a page score system. This score is calculated based on a number of factors to determine the relevance of a page to a user's search terms. These factors include:

  • the number of times the searched term appears on that page
  • the number of search terms that appear on the page
  • the individual words that form part of an 'exact phrase' query
  • whether the word appears in the title, meta description, or meta keywords part of the page
Changing the search parameters

From the results page the search can be performed on the web site by clicking on the Results from ESDS Qualidata web site top tab.

There is also an option to extend the search to all of the Data Catalogue or one of the other ESDS specialist data services.

The search parameters can also be changed by the use of the any search words/all search words option.

All Fields - Advanced Search
A search on All Fields will search on all of the catalogue record with the exception of the access conditions.

Title - Advanced Search

A search in the Title field is performed on all elements within the title i.e. main title, sub-title, alternative title and series title. A truncation search is recommended if the full title is not known.

Note: A truncation search will not work when the Exact button is checked.
Subject - Advanced Search

A Subject search can be used to locate datasets whose subject coverage reflects the area of interest of the user e.g. health care, social networks, voting behaviour. The studies located might be wholly about the subject area or have variables/questions covering the subject. In the Advanced Search this is performed on several areas of the catalogue record: the subject category, abstract, main topics and subject keyword list.

  • Subject Categories:
    One or more subject categories, selected from the UKDA list of subject categories, are assigned to each dataset to reflect the overall subject scope of the dataset.

    The subject category list reflects the subject scope of the data collection. There are 20 thematic headings which, in most cases, are further divided into subheadings. The full list can be viewed on the Browse by subject page. From this page a separate browse function is available allowing users to browse the full data collection for datasets matching their area of interest.

    One or more boxes within a category can be checked to retrieve datasets on the required topic(s). Alternatively selecting a main heading (e.g. Politics) will retrieve studies on ALL areas within this category.

    Note: It is not possible to select from more than one category group within the same search.

    Titles are returned in date order - latest first.

  • Abstract and Main Topics:
    The abstract and main topics contain information on the aims, purpose and background to the data collection, they also list the key themes and topics or variables covered by the data.
  • Keywords:
    Each catalogue record contains a list of assigned subject Keywords covering all topics included in the data. The keywords are taken from a controlled vocabulary list held in the UKDA thesaurus, HASSET, which is available to help decide on the appropriate search term.

    In the Subject search, the keyword list is just one of the fields being searched on (the others being the abstract, main topics and the subject categories) - this provides a broad search, retrieving datasets where the search term(s) can be anywhere within these fields. This is in contrast to the Keyword search, where the search is confined to the controlled subject keyword list. See Keyword - Advanced Search below.

Keyword - Advanced Search

The Keyword search performs a free-text search on the list of keywords assigned to each study. More than one term can be entered in the search box and the Any All Exact buttons used, or terms can be entered in more than one box and combined with the AND NOT OR operators.

Examples:
  • select Keyword from the drop-down list and enter crime in the search box and check the Any box - this will result in a list of datasets with keywords containing the word crime; it will include such things as crime, crime victims, fear of crime
  • enter fear of crime in the search box and check the Exact box - this will locate datasets which have been assigned the keyword fear of crime

If the original search term retrieves no studies (i.e. it does not match or partially match a keyword) or if help is required in choosing appropriate keywords, then the HASSET thesaurus is available either to consult for suggested terms or as a stand-alone search tool. See Thesaurus-aided keyword search using HASSET below.

Thesaurus-aided keyword search using HASSET

The thesaurus-aided search using the Humanities and Social Science Electronic Thesaurus - HASSET allows a more precise search than the keyword search.

Entering a search term (consisting of one or more words) in the HASSET interface will result in either a match with the word in the thesaurus or, if there is no exact match, a listing of partial matches. A matched term will automatically be displayed in its position in the thesaural structure showing its relationship to other terms. From here broader, narrower, or related terms may be selected to refine or extend the search. If there is only a partial match then selecting a term from the resulting listing will display the thesaurus view for that term.

Once an appropriate keyword has been found in the thesaurus, a search can be carried out on the Data Catalogue by clicking the Search on Keyword button. This will retrieve datasets to which the keyword has been assigned.

To search the catalogue for one or more terms simultaneously, check the boxes to include Narrower terms and/or Related terms then click on the Search on Keyword button.

Note: Searching on multiple terms can resuly in a slower response time.

It is currently not possible to combine this thesaurus-aided search with other elements of the catalogue search. Thus if a user wishes to search on a specific thesaurus keyword combined with e.g. year, geographical coverage, then once the desired keyword(s) in HASSET have been identified, they should be manually entered into the appropriate field in the catalogue search.

Geography - Advanced Search

A search on Geography can be performed to locate data which cover a particular geographic coverage: country, county, region, city/town or village etc. Two or more geographic areas can be combined within one search box using the Any or All buttons, or in separate search boxes by using the AND NOT OR operators on the left hand side.

Data at national or subnational level, or covering more than one country, can also be located.

Examples:

  • a search on Scotland will pick up any studies with a geographic coverage of Scotland at a national level, as well as data that covers only parts of Scotland (subnational)
  • to find data on Scotland at a national level search Scotland and national using the AND operator on the left hand side
  • to find subnational level data search on Scotland and subnational using the AND operator on the left hand side
  • data covering more than one country may be retrieved by searching on the term cross-national
  • to locate global or world data use the search term multi-nation
  • it is advisable to search on a full name rather than abbreviation e.g. Great Britain not GB
  • when searching on a two or more word country e.g. Great Britain, Republic of Ireland the Exact button should be checked
Geographic terms can also be viewed in the HASSET thesaurus and can be used in either a Geography or a Keyword search.
Data Creator/Funder - Advanced Search

This search is performed on all individuals or organisations associated with the creation of the data e.g. principal investigator, data collector, depositor, funder.

  • Searching on a personal name:

    Names usually appear in the catalogue record in the format surname, followed by initial(s), e.g. Crewe, I. rather than I. Crewe or Ivor Crewe. However as some initials will be classed as 'skip' words and will therefore be discounted from the search, it is strongly recommended to search on surname only.

  • Searching for an organisation:

    Names of organisations are usually entered in the catalogue record in full e.g. Economic and Social Research Council rather than as an acronym e.g. ESRC. It is therefore advisable to search for both the full name and the abbreviation by using the first two boxes, check the Exact buttons and combining with the OR operator.

Methodology - Advanced Search

A search on Methodology is performed on Time Dimensions, Sampling Procedures and Method of Data Collection. These fields are populated from controlled vocabulary lists i.e. they use standard terminology to ensure consistency. Using these controlled vocabularies as search terms ensures consistent and effective retrieval. The terms currently used are listed below:

  • Time Dimensions
    • Cross-sectional (one-time) study
    • Follow-up to cross-sectional study
    • Repeated cross-sectional study
    • Longitudinal/panel/cohort study
    • Time Series
  • Sampling Procedures
    • No sampling (total universe)
    • Quota sample
    • Simple random sample
    • One-stage stratified or systematic random sample
    • One-stage cluster sample
    • Multi-stage stratified random sample
    • Quasi-random (e.g. random walk) sample
    • Purposive selection/case studies
    • Volunteer sample
    • Convenience sample
  • Method of Data Collection
    • Face-to-face interview
    • Telephone interview
    • Postal survey
    • Self-completion
    • Psychological measurements
    • Educational measurements
    • Observation
    • Clinical measurements
    • Simulation
    • Diaries
    • Physical measurements
    • Transcription of existing materials
    • Compilation or synthesis of existing material
    • Focus group
    • Video recording
    • Audio recording
Publications - Advanced Search

Select Publications to search on publications or reports resulting from the primary or secondary analysis based on the data. This search works on all areas of the publications lists (bibliographic references) that accompany the study description. A search may be carried out on author (it is recommended to use surname only), title, publisher, etc.

UKDA Study Number - Advanced Search

This is a quick, simple search to locate a study where the UKDA study number is known. More than one study number may be searched at a time (it is advisable to check the Any box).

Time Period - Advanced Search

Searches can be focused to locate data covering a particular year or a span of years:

  • Single year

    Entering a single year in the first box will locate all studies covering the specific year as well as studies with a date span which includes the specific year. For example, a search on 2007 will return studies with the following dates: 2007, 1995-2007, 2001-2008, 2007-2008, etc.

  • Year range

    Entering the start year in the first box and the ending year in the second box will locate studies that have data both covering and spanning the range of years entered. For example, a search on the year span 1990-2001 will locate studies with data covering 1990, 1991,...etc, 1980-1999, 1990-2008, 1989-2001, etc.

Results - Advanced Search

The number of hits for the search is displayed at the top of the list. There is no maximum limit to the number of hits retrieved, however where a search results in 100 or more hits only the first 100 are displayed with the option to Display All if desired. Depending on the number of records being displayed this may result in a slow response.

Sort by Relevance - Advanced Search

The ranking used in the sort by Relevance is fair similarity - this means that datasets are ranked according to how many times the search term or terms appear in the record. Sort by relevance is the default.

Sort by Date - Advanced Search

Sort by Date is ordered by the date of coverage of the data - with the most recent first.
