Lucene index inside of a database

Question

is it possible to do this? i have an oracle db and wondering if storing an index inside may be the most efficient way to go vs storing the index on a file system. has anyone done this before? is it possible with lucene version 3.x?

Answer 1

It's possible using the Lucene Directory interface, but it's not easy. Many people have tried, but you get terrible performance. The reason is that to execute a search, you have to read the entire index (or segment) out of the database as a blob and run the search on top of it. Very inefficient.
