Afternoon chaps,
After my adventures with Zend-Lucene-Search, and discovering it isn\'t all its cracked up to be when indexing large datasets, I\'ve turned to Solr
Never used Zend before, but I've used Lucene/Solr.
Are you using the same version of Lucene for both the Solr indexing and the Zend port? Check to see what Lucene jar file is being used for each. If they're different, then Solr might be producing a Lucene index that isn't compatible with the Zend port.
