Generally, no.

You can probably attempt to implement your own format but this would require a lot of effort.

If there are scale-able environments(multiple environments for load balancing) than how lucene will work ? – Umair Saleem May 14 '13 at 05:16

I am not entirely sure what you have meant by your question, but I'd suggest you to read [this article](http://searchhub.org/2009/09/02/scaling-lucene-and-solr/) which covers Lucene/Solr scalability topic in great detail. – mindas May 14 '13 at 09:04

I am no expert in Lucene, but I know that it is optimized to offer fast search over the filesystem. So it would be theoretically possible to build a Lucene index over the database, but the main feature of lucene (being a VERY fast search engine) would be lost.

+1 Only local file-system based directories offer acceptable performance. – jpountz May 14 '13 at 10:24

As a point of interest, Compass supported storage of a Lucene index in a database, using a JdbcDirectory. This was, as far as I can figure, just a bad idea.

Compass, by the way, is now defunct, having been replaced by ElasticSearch.
