Class SirenQParser

java.lang.Object

org.apache.solr.search.QParser

org.sindice.siren.solr.qparser.SirenQParser

Direct Known Subclasses:

JsonQParser, KeywordQParser

public abstract class SirenQParser
extends org.apache.solr.search.QParser

The SirenQParser is in charge of parsing a SIREn query request.

Expand the query to multiple fields by constructing a disjunction of the parsed query across the fields.

For each nested parameter in the request, its argument is parsed as a subquery and added to the main query.

The default operator for use by the query parsers is StandardQueryConfigHandler.Operator.AND. It can be overwritten using the parameter QueryParsing.OP.
