createWeight
public Weight createWeight(Searcher searcher)
Description copied from class:Query
Expert: Constructs an appropriate Weight implementation for this query.Only implemented by primitive queries, which re-write to themselves.
- Overrides:
createWeight
in classQuery
-
extractTerms
public void extractTerms(Set<Term> terms)
Description copied from class:Query
Expert: adds all terms occurring in this query to the terms set. Only works if this query is in itsrewritten
form.- Overrides:
extractTerms
in classQuery
-
toString
public String toString(String field)
Description copied from class:Query
Prints a query to a string, withfield
assumed to be the default field and omitted.The representation used is one that is supposed to be readable by
QueryParser
. However, there are the following limitations:- If the query was created by the parser, the printed representation may not be exactly what was parsed. For example, characters that need to be escaped will be represented without the required backslash.
- Some of the more complicated queries (e.g. span queries) don't have a representation that can be parsed by QueryParser.
