Just a quick note that version 2.1.2 of the wpSearchMu plugin went live today. I’ve fixed a fairly common “Uncaught exception Zend_Search_Lucene_Exception” problem that would crop up and require an index rebuild. After you update, you shouldn’t see that error anymore.
I’ve also added a few checks to make sure that the plugin is installed in the correct location. Quite a few people aren’t installing to the mu-plugins folder, and that was causing some index inconsistencies and errors.
Head over to the wpSearchMu page to download the latest version!
