Comment 1 for bug 787151

A full text search without caching is fairly trivial to implement, you could
just combine code from the extract ISBN and Find Duplicates plugins. With caching is a
little harder and that is indeed on of the things on my long term TODO list. I
don't like leaving tickets open that are not going to get addressesd in the
near future, so I'm closing. If someone wants to start work on thi feature,
feel free to re-open.
