Subject: Keep DotLucene indexes Safe


I'm doing some tests using DotLucene (with Wikipedia data) and I have some
question about Lucene.NET.

1) I'm using multiple threads to index documents and one thread to write
RamDirectory indexes on disk ( as only one writer is allowed). Bu using that
mechanism and the MergeIndexes methods, an Optimize is done before each
merge.That optimize remove all interest of creating Memory indexes.
Right ? It seems much faster to add Document sequencially instead of Merging
RAMDirectory indexes.

2) Can an Optimise corrupt an index ?
I've ran into that problem using Luke to optimise an index (about 2Gb never
optimised). Once the Optimise was done, my index was corrupted.
Any idea ?

Thanks a lot for your time and your work.
