Class TermFilteredPresearcher

  • Direct Known Subclasses:

    public class TermFilteredPresearcher
    extends Presearcher
    Presearcher implementation that uses terms extracted from queries to index them in the Monitor, and builds a disjunction from terms in a document to match them.

    Handling of queries that do not support term extraction through the QueryVisitor API can be configured by passing a list of CustomQueryHandler implementations.

    Filtering by additional fields can be configured by passing a set of field names. Documents that contain values in those fields will only be checked against MonitorQuery instances that have the same fieldname-value mapping in their metadata.
