NAME¶
Plucene::Search::PhraseQuery - A query that matchs a phrase
SYNOPSIS¶
# isa Plucene::Search::Query
DESCRIPTION¶
A Query that matches documents containing a particular sequence of terms.
A phrase query represents a query that is matched against a consecutive sequence
of terms in the field. For example, the phrase query 'winding road' should
match 'winding road' but not 'road winding' (with the exception of more
relaxed slop factors).
Phrase queries are represented in Plucene's API by instances of the PharseQuery
class. These instances contain an ordered list of Term objects that represent
the terms to match. For obvious reasons, all terms in a PhraseQuery must refer
to the same field.
A phrase query may have an optional boost factor and an optional slop parameter
(default = 0). The slop parameter can be used to relax the phrase matching by
accepting somewhat out of order sequences of the terms.
METHODS¶
add¶
Adds a term to the end of the query phrase.
sum_squared_weights¶
The sum squared weights of this query.
normalize¶
Normalize the query.
to_string¶
Prints a user-readable version of this query.
