Field Based Search
Users can search within specific fields. This produces more precise search results. It is also faster than a search through the complete records.
For example, if you search for a document with a specific title, you get
better results if you use a field based search in the
rm_title field instead of searching all records in
general.
By default, field based search is available for all indexed fields.
Field based search on text fields allows to use all CORE query features. On numeric or date fields, you can search for equal, lesser or greater values.
Advanced information
Field based search is internally used to implement several other
features. For this purpose, each indexed field is implicitly enabled for field
based search using the field name prefixed with
_internal_ as
abbreviation. In contrast to explicitly defined abbreviations,
this is case sensitive.
Important: Use of the implicit abbreviations is reserved for the CORE API. Applications may not provide these in the UI for end users. For use in search expressions, you must always explicitly define abbreviations.
