Version 0.9.3 of the PECL extension for solr has just been released. Some of the methods have been updated and more get* methods have been added to the Query builder classes.
The user level documentation was also updated to make the installation instructions a lot clearer. The latest documentation and source code are available from the project home page http://pecl.php.net/package/solr -- "Good Enough" is not good enough. To give anything less than your best is to sacrifice the gift. Quality First. Measure Twice. Cut Once.
