EQL Record Filters

This section describes how to configure and use EQL record filters.

About EQL record filters
EQL record filters let you define arbitrary subsets of the total record set, and dynamically restrict search and navigation results to these subsets.
SelectionFilter format
The SelectionFilter type is a record filter that uses EQL query syntax.
DataSourceFilter format
The DataSourceFilter type is similar in format to the SelectionFilter type.
EQL operators for filterString filters
The filterString version of EQL record filters are specified with WHERE clause types of Boolean expressions.
Language codes for EQL error messages
You can set the language to be used for EQL parsing error messages.
Range filters
EQL filters allow a user, at request time, to specify an arbitrary, dynamic range of values that are then used to limit the records returned for a navigation query.
Geocode filters
When used with a standard attribute of type geocode, the EQL DISTANCE function indicates a filter based on the distance of that geocode attribute from a given reference point.
Managed attribute hierarchy filters
An EQL record filter can specify managed attribute values for the search criteria.
Boolean attribute filters
Filtering by Boolean attribute assignments is supported.
Using EQL filters with record and value searches
Either or both of the EQL record filters can be used with a record search or a value search.
EQLConfig requests
The EQLConfig complex type allows you to send arbitrary EQL statements for evaluation.
