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.

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.
