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
url - the webservice base url
agent - a user agent object
autocommit - a boolean value for automatic commit() after add/update/delete (default: enabled)
default_params - a hashref of parameters to send on every request
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:
overwrite (default: true) - Replace previously added documents with the same uniqueKey
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:
maxSegments (default: 1) - Optimizes down to at most this number of segments
waitFlush (default: true) - Block until index changes are flushed to disk
waitSearcher (default: true) - Block until a new searcher is opened
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 ).
