Direct Known Subclasses:

SolrPluginUtils.DisjunctionMaxQueryParser

public class SolrQueryParser
extends QueryParser

A variation on the Lucene QueryParser which knows about the field types and query time analyzers configured in Solr's schema.xml.

This class also deviates from the Lucene QueryParser by using ConstantScore versions of RangeQuery and PrefixQuery to prevent TooManyClauses exceptions.

If the magic field name "_val_" is used in a term or phrase query, the value is parsed as a function.
