Clinical Trials Fieldsets

Fieldsets are used to specify fields groups in the context of a return statement.

Clinical Trials Indicators

Indicators are used to aggregate results in the context of a facet query.

Indicator	Description
count	Total count

Clinical Trials Search Indexes

Search indexes are used to perform full-text searches on the source they belong to. The default search index, which is used if none other is specified, is full_data.

Search index	Supports multi-index search	Description
title_only	✓	Search for keywords in title only.
title_abstract_only	✓	The keywords will be searched for in the title and description/summary.
raw_affiliations	✓	Search within the raw names of the involved research organizations. Note: Depending on the selected content type the organizations can have different roles: Publications (author affiliation), Grants (funded organization/investigator affiliations), Patents (current and original assignee), Clinical trials (sponsor and collaborating organization). Boolean nesting to process phrases or words in a specified order is not supported.
investigators		Search for keywords in the investigators fields of a clinical trial.
full_data	✓	The keyword will be searched for in all data fields that are found for that document. In cases where the full text is indexed in the background this will also be searched, even though the full text may not be available to see within Dimensions itself. This will mean that many results that are returned may not include mention of the searched keyword on the document page, but are returned in the search because the keyword can be found in the full text which cannot be read.
