NAME

LucyX::Search::ProximityQuery - Query matching an ordered list of terms.

SYNOPSIS

my $proximity_query = LucyX::Search::ProximityQuery->new( 
    field  => 'content',
    terms  => [qw( the who )],
    within => 10,    # match within 10 positions
);
my $hits = $searcher->hits( query => $proximity_query );

DESCRIPTION

ProximityQuery is a subclass of Query for matching against an ordered sequence of terms.

CONSTRUCTORS

new

my $proximity_query = LucyX::Search::ProximityQuery->new(
    field  => $field   # required
    terms  => $terms   # required
    within => $within  # required
);

Create a new ProximityQuery.

• field - The field that the phrase must occur in.

• terms - The ordered array of terms that must match.

METHODS

get_field

my $string = $proximity_query->get_field();

Accessor for object’s field attribute.

get_terms

my $arrayref = $proximity_query->get_terms();

Accessor for object’s array of terms.

get_within

my $int = $proximity_query->get_within();

Accessor for object’s within attribute.

make_compiler

my $compiler = $proximity_query->make_compiler(
    searcher    => $searcher     # required
    boost       => $boost        # required
    subordinate => $subordinate  # default: false
);

Abstract factory method returning a Compiler derived from this Query.

• searcher - A Searcher.

• boost - A scoring multiplier.

• subordinate - Indicates whether the Query is a subquery (as opposed to a top-level query). If false, the implementation must invoke normalize() on the newly minted Compiler object before returning it.
