Method GetPrefixQuery
GetPrefixQuery(String, String)
Factory method for generating a query (similar to GetWildcardQuery(String, String)). Called when parser parses an input term token that uses prefix notation; that is, contains a single '*' wildcard character as its last character. Since this is a special case of generic wildcard term, and such a query can be optimized easily, this usually results in a different query object.
Depending on settings, a prefix term may be lower-cased automatically. It will not go through the default Analyzer, however, since normal Analyzers are unlikely to work properly with wildcard templates.
Can be overridden by extending classes, to provide custom handling for wild card queries, which may be necessary due to missing analyzer calls.
