NAME ^

Search::Query::Dialect::Lucy - Lucy query dialect

SYNOPSIS ^

 my $query = Search::Query->parser( dialect => 'Lucy' )->parse('foo');
 print $query;
 my $lucy_query = $query->as_lucy_query();
 my $hits = $lucy_searcher->hits( query => $lucy_query );

DESCRIPTION ^

Search::Query::Dialect::Lucy extends the Lucy::QueryParser syntax to support wildcards, proximity and ranges, in addition to the standard Search::Query features.

METHODS ^

This class is a subclass of Search::Query::Dialect. Only new or overridden methods are documented here.

init

Overrides base method and sets SWISH-appropriate defaults. Can take the following params, also available as standard attribute methods.

wildcard

Default is '*'.

allow_single_wildcards

If true, terms like '*' and '?' are allowed as valid. If false, the Parser will croak if any term consists solely of a wildcard.

The default is false.

fuzzify

If true, a wildcard is automatically appended to each query term.

ignore_order_in_proximity

If true, the terms in a proximity query will be evaluated for matches regardless of the order in which they appear. For example, given a document excerpt like:

 foo bar bing

and a query like:

 "bing foo"~5

if ignore_order_in_proximity is true, the document would match. If ignore_order_in_proximity is false (the default), the document would not match.

stringify

Returns the Query object as a normalized string.

stringify_clause( leaf, prefix )

Called by stringify() to handle each Clause in the Query tree.

as_lucy_query

Returns the Dialect object as a Lucy::Search::Query-based object. The Dialect object is walked and converted to a Lucy::Searcher-compatible tree.

field_class

Returns "Search::Query::Field::Lucy".
