3) Sounds you want to use Lucene for storage, without databases like mysql. It may work, but hard for later data management. 1) and 2) You can use mysql as main storage, and pull data out to create Lucene indexes. Pay attention to incremental changes. It's a continuous process, not one-time data import. Or you would have to put a hook in your program to write new content to the index. Anyway, you can get it work, but maybe not as simple as you expected.

Hi,

Normally, when I am building my index directory for indexed documents, I
used to keep my indexed files simply in a directory called 'filesToIndex'.
So in this case, I do not use any standar database management system such
as mySql or any other.

1) Will it be possible to use mySql or any other for the purpose of manage
indexed documents in Lucene?

2) Is it necessary to follow such kind of methodology with Lucene?

3) If we do not use such type of database management system, will there be
any disadvantages with large number of indexed files?

Appreciate any reply from you.
Thanks,
Manjula.
