Search::Query::Dialect::Lucy - Lucy query dialect
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 );
Search::Query::Dialect::Lucy extends the Lucy::QueryParser syntax to support wildcards, proximity and ranges, in addition to the standard Search::Query features.
This class is a subclass of Search::Query::Dialect. Only new or overridden methods are documented here.
Sets Lucy-appropriate defaults. Can take the following params, also available as standard attribute methods.
Default is '*'.
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.
If true, a wildcard is automatically appended to each query term.
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:
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.
Returns the Query object as a normalized string.
Called by stringify() to handle each Clause in the Query tree.
Returns the Dialect object as a Lucy::Search::Query-based object. The Dialect object is walked and converted to a Lucy::Searcher-compatible tree.
