Patents Fieldsets

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

Fieldset	Fields

Patents Indicators

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

Patents 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 in the title and description/summary.
title_abstract_claims	✓	Search for keywords in the title, abstract and claims of a patent.
inventors		Search for inventors
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.
assignees	✓	Search for assignees names (including both current_assignees and original_assignees fields)
