Hello,
I have read the parallel reader doc. It says it must have the same number of
documents as the other index.
When we are using a writer - searcher combination, how can we integrate this
parallel reader into game.
Simply, I have some documents, and I just like to mark them, in an efficient

One option is to index the new field in sync (same index order) into
a new index, and search using a ParallelIndexReader.

Woops -- disregard this! Chris' approach will work. And, we don't

Really what we need is a new "addParallellIndices" method. I think,

asuming you have indexes that work in conjunction with eachther they
way you want when using ParallelReader, you should (in theory) be able to
use...
ParallelReader r = ...;
IndexWriter w = new
I was actually thinking of creating a separate index with only the extra
field and them modify the other index (change some files etc.)
Sounds hacky. Dunno if its possible.
Thanks

Just beware, though, that with ParallelReader you must ensure that
the internal docIDs of both indices remain "aligned" over time.
If you never do deletions, then that happens for free.
If you do deletions, then, you must change IndexWriter to buffer by
doc count (same doc count for all wr

Hi all:
We have a large index and it is difficult to reindex.
We want to add another field to the index without reindexing, e.g. just
create a new inverted index, dictionary files etc.
How feasible is it to add this to lucene?
Thanks
