MatchAllDocsQuery
public MatchAllDocsQuery()
createWeight
protected Weight createWeight(Searcher searcher)
Expert: Constructs an appropriate Weight implementation for this query.
Only implemented by primitive queries, which re-write to themselves.
- createWeight in interface Query
equals
public boolean equals(Object o)
extractTerms
public void extractTerms(Set terms)
Expert: adds all terms occuring in this query to the terms set. Only
works if this query is in its
rewritten
form.
- extractTerms in interface Query
hashCode
public int hashCode()
toString
public String toString(String field)
Prints a query to a string, with
field
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.
- toString in interface Query
