NAME

       WebService::Solr - Module to interface with the Solr (Lucene) webservice

SYNOPSIS

	   my $solr = WebService::Solr->new;
	   $solr->add( @docs );

	   my $response = $solr->search( $query );
	   for my $doc ( $response->docs ) {
	       print $doc->value_for( $id );
	   }

DESCRIPTION

       WebService::Solr is a client library for Apache Lucene's Solr; an enterprise-grade indexing and searching platform.

ACCESSORS

       o   url - the webservice base url

       o   agent - a user agent object

       o   autocommit - a boolean value for automatic commit() after add/update/delete (default: enabled)

       o   default_params - a hashref of parameters to send on every request

       o   last_response - stores a WebService::Solr::Response for the last request

HTTP KEEP-ALIVE
       Enabling HTTP Keep-Alive is as simple as passing your custom user-agent to the constructor.

	   my $solr = WebService::Solr->new( $url,
	       { agent => LWP::UserAgent->new( keep_alive => 1 ) }
	   );

       Visit LWP::UserAgent's documentation for more information and available options.

METHODS

   new( $url, \%options )
       Creates a new WebService::Solr instance. If $url is omitted, then "http://localhost:8983/solr" is used as a default. Available options are
       listed in the ACCESSORS section.

   BUILDARGS( @args )
       A Moose override to allow our custom constructor.

   add( $doc|@docs, \%options )
       Adds a number of documents to the index. Returns true on success, false otherwise. A document can be a WebService::Solr::Document object or
       a structure that can be passed to "WebService::Solr::Document->new". Available options as of Solr 1.4 are:

       o   overwrite (default: true) - Replace previously added documents with the same uniqueKey

       o   commitWithin (in milliseconds) - The document will be added within the specified time

   update( $doc|@docs, \%options )
       Alias for "add()".

   delete( \%options )
       Deletes documents matching the options provided. The delete operation currently accepts "query" and "id" parameters. Multiple values can be
       specified as array references.

	   # delete documents matching "title:bar" or uniqueId 13 or 42
	   $solr->delete( {
	       query => 'title:bar',
	       id    => [ 13, 42 ],
	   } );

   delete_by_id( $id )
       Deletes all documents matching the id specified. Returns true on success, false otherwise.

   delete_by_query( $query )
       Deletes documents matching $query. Returns true on success, false otherwise.

   search( $query, \%options )
       Searches the index given a $query. Returns a WebService::Solr::Response object. All key-value pairs supplied in "\%options" are serialzied
       in the request URL.

   auto_suggest( \%options )
       Get suggestions from a list of terms for a given field. The Solr wiki has more details about the available options
       (http://wiki.apache.org/solr/TermsComponent)

   commit( \%options )
       Sends a commit command. Returns true on success, false otherwise. You must do a commit after an add, update or delete. By default,
       autocommit is enabled.  You may disable autocommit to allow you to issue commit commands manually:

	   my $solr = WebService::Solr->new( undef, { autocommit => 0 } );
	   $solr->add( $doc ); # will not automatically call commit()
	   $solr->commit;

       Options as of Solr 1.4 include:

       o   maxSegments (default: 1) - Optimizes down to at most this number of segments

       o   waitFlush (default: true) - Block until index changes are flushed to disk

       o   waitSearcher (default: true) - Block until a new searcher is opened

       o   expungeDeletes (default: false) - Merge segments with deletes away

   rollback( )
       This method will rollback any additions/deletions since the last commit.

   optimize( \%options )
       Sends an optimize command. Returns true on success, false otherwise.

       Options as of Solr 1.4 are the same as "commit()".

   ping( )
       Sends a basic ping request. Returns true on success, false otherwise.

   generic_solr_request( $path, \%query )
       Performs a simple "GET" request appending $path to the base URL and using key-value pairs from "\%query" to generate the query string. This
       should allow you to access parts of the Solr API that don't yet have their own correspodingly named function (e.g. "dataimport" ).
