Manual Reference Pages - SOLR (3)
Solr - Perl extension for interfacing with Solr, a lucene based search engine.
my $solr = Solr->new(schema=>"/home/garafolat/cpan/Solr/schema.xml",
#NOTE: timeout is an optional param for each method and is used by LWP to pass a timeout
for waiting for a response result code from Solr. It defaults to 600 seconds if not supplied
$solr->add($hashRef, $timeout); # Takes a reference to a hash of hashes of fields and values,
creates solr xml, and posts to server defined in constructor.
Note: An update is performed by adding a document with an existing
$solr->add_by_file($file, $timeout); # simply posts a file. The file must be in valid solr
xml add syntax matching your solr servers schema for field requirements.
$solr->post_file($file,$timeout); # posts file to solr server. Differs from add_by_file only in logging
$solr->delete_by_id($id,$timeout); # Deletes by field declared as uniqueID in solrs schema.xml
$solr->delete_by_query($query,$timeout); # Deletes by query string provided
$solr->commit(); # commits adds and deletes
$solr->optimize($timeout); # issues a post to solr server that causes it to perform an optimze
# timeout is an optional parameter expressed in seconds before
# LWP stops waiting for a return result code from Solr. Defaults
# to 600 if not supplied.

A Note On Logging
Solr.pm uses Log4perl for logging. Log4perl is a perl port of log4j.
to disable logging set the optional initialization variable disable_logging=>1.

NOTE on Adding documents
Currently there is no error checking for in add_by_file and add methods. It is possible to implement
such checking using the schema object to compare fields in schema with the data structure passed into add
or the file referenced in add_by_file. I havent implemented this yet, as the simply catching a
non zero result code from the solr server is sufficient for my needs in notifying of an error at this time.
This module provides a set of methods for adding (updating) and deleting entries in an existing solr server.
None by default.
THINGS TO DO
-Add options to pass optional parameters to Solr in various post methods
-Add solr search query functionality and parsing of:
a) xml results
b) user defined result formats
-Incorporate Error checking of adds and deletes:
a) Level 1, check for proper syntax
b) Level 2, compare posts against schema for sanity check
