Public Constructors

public MatchAllDocsQuery ()

public MatchAllDocsQuery (String normsField)

Parameters
normsField Field used for normalization factor (document boost). Null if nothing.

Public Methods

public Weight createWeight (Searcher searcher)

Expert: Constructs an appropriate Weight implementation for this query.

Only implemented by primitive queries, which re-write to themselves.

public boolean equals (Object o)

public void extractTerms (Set<Term> terms)

Expert: adds all terms occurring in this query to the terms set. Only works if this query is in its rewritten form.

public int hashCode ()

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.
