Search Tips


Use keywords to find relevant data. Data Catalog matches these keywords to terms found in the Titles, Descriptions and other relevant fields. For example search using keywords "diabetes", "study".

Following your search, a list of datasets matching your query will be displayed.

Your results are sorted by relevance, i.e. how closely they match your search terms (priority is given to the titles of the datasets).

You can also refine your search using options below the search field: ‘all of these words’, ‘any of these words’ or ‘none of these words’.


Another way to find data is by filtering. You will find a list of filters to the left of your search results. You can use these filters to customise your search and find exactly what you are looking for.

You can select multiple filters. To remove a filter, just click on its name or on the cross sign next to it.

Boolean search

Boolean search is a type of search that allows you to combine keywords with operators (or modifiers), such as ‘AND’, ‘NOT’ and ‘OR’ to broaden and/or narrow your search.

  • AND includes both search terms. It corresponds to the option ‘all of these words’.
  • OR allows you to broaden your search with multiple terms. It corresponds to the ‘any of these words’ search option.
  • NOT excludes a specific term, for example NOT (diabetes OR asthma). It corresponds to the 'none of these words' search option.
  • Quotation marks (" ") are used to search for an exact phrase. For example: "medical implants"
