METHODS

type

Returns Lucy.

aggregator_class

Passed as param to new(). This class is used for filtering incoming docs via the aggregator's swish_filter() method.

auto_commit( 0 | 1 )

Set this in new().

If true, a new indexer is spawned via init_indexer() for each POST, PUT or DELETE.

If false, the same indexer is re-used in POST, PUT or DELETE calls, until COMMIT or ROLLBACK is called.

Default is true (on).

BUILD

Overrides base method to load the aggregator_class and other Engine-specific construction tasks.

init_searcher

Returns a Dezi::Lucy::Searcher object.

init_indexer

Returns a Dezi::Lucy::Indexer object (used by the REST API).

init_suggester

Returns a LucyX::Suggester object. You can configure it as described in the SYNOPSIS.

build_facets( query, results )

Returns hash ref of facets from results. See Search::OpenSearch::Engine.

process_result( args )

Overrides base method to preserve multi-value fields as arrays.

has_rest_api

Returns true.

get_allowed_http_methods

Returns array (not an array ref) of supported HTTP method names. These correspond to the UPPERCASE method names below.

NOTE that COMMIT and ROLLBACK are not official HTTP/1.1 method names.

PUT( doc )

Writes doc to the first index defined. doc must already exist.

POST( doc )

Writes doc to the first index defined. doc may be new or already exist.

DELETE( uri )

Deletes uri from all indexes.

GET( uri )

Fetches uri from all indexes.

COMMIT

If auto_commit is false, use this method to conclude a transaction.

ROLLBACK

If auto_commit is false, use this method to abort a transaction.
