Zend Lucene and Java Lucene are built in PHP and java repectively, and PHP language has a higher level than java.
Just wondering How big the performance difference among these two, regarding to index building and data searching?
Is it much more effective to let java create and rebuild index, and let php use the index?

This is a quote from a Zend Certified Engineer.\n\n\n Against my better judgment, the\n company I work for migrated our\n previous search solution to\n Zend_Search_Lucene. On pretty\n heavy-duty hardware, indexing a\n million documents took several hours,\n and searches were relatively slow. The\n indexing process consumed vast amounts\n of memory, and the indexes frequently\n became corrupted (using 1.5.2). A\n single wild card search literally\n brought the web server to its knees,\n so we disabled that feature. Memory\n usage was very high for searches, and\n as a result requests per second\n necessarily declined heavily as we had\n to reduce the number of Apache child\n processes.\n \n We have since moved to Solr (a\n Lucene-based Java search server) and\n the difference is dramatic. Indexing\n now takes around 10 minutes and\n searches are lightning fast. What a\n difference a language makes.\n\n\nOriginal Article\n\nIn this case, Java.",
