/**
* Starting point for the Solr API. Represents a Solr server resource and has
* methods for pinging, adding, deleting, committing, optimizing and searching.
*
* Example Usage:
* <code>
* ...
* $solr = new Apache_Solr_Service(); //or explicitly new Apache_Solr_Service('localhost', 8180, '/solr')
*
* if ($solr->ping())
* {
* $solr->deleteByQuery('*:*'); //deletes ALL documents - be careful :)
*
* $document = new Apache_Solr_Document();
* $document->id = uniqid(); //or something else suitably unique
*
* $document->title = 'Some Title';
* $document->content = 'Some content for this wonderful document. Blah blah blah.';
*
* $solr->addDocument($document); //if you're going to be adding documents in bulk using addDocuments
* //with an array of documents is faster
*
* $solr->commit(); //commit to see the deletes and the document
* $solr->optimize(); //merges multiple segments into one
*
* //and the one we all care about, search!
* //any other common or custom parameters to the request handler can go in the
* //optional 4th array argument.
* $solr->search('content:blah', 0, 10, array('sort' => 'timestamp desc'));
* }
* ...
* </code>
*
* @todo Investigate using other HTTP clients other than file_get_contents built-in handler. Could provide performance
* improvements when dealing with multiple requests by using HTTP's keep alive functionality
