public MatchAllDocsQuery()
createWeight
protected 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 class Query
toString
public java.lang.String toString(java.lang.String field)
- Description copied from class:
Query
- Prints a query to a string, with
field
as the default field
for terms. 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.
- Specified by:
toString
in class Query
equals
public boolean equals(java.lang.Object o)
- Overrides:
equals
in class java.lang.Object
hashCode
public int hashCode()
- Overrides:
hashCode
in class java.lang.Object
