Subject ParallelReader
Date Mon, 21 Feb 2011 08:39:17 GMT
Hello everybody,

I was wondering, if someone could point me to what I need to be aware of, using a ParallelReader.

My intention is to modify Nutch (http://nutch.apache.org/) in a way, that in the Lucene-index
Nutch uses, only documents for changed websites are updated. 

However, due to the existing scoring-algorithms, most page's page-score will change. After
doing some research about updating single fields in a Lucene-index, I found http://wiki.apache.org/lucene-java/ParallelIncrementalIndexing
This brought me to the idea, to create a separate index for the page-scores. 

Are there maybe any other approaches around, that I overlooked? What do I need to be aware
of, when using two parallel indices?


Thanks for any help!

David
