Thanks Ian.

I may need to use IndexSearcher(Reader, ExecutorService). I have sharded my 
index. Say if i have 10 indexes then i will have 10 IndexSearchers. How to use 
this API. It takes one Reader and ExecutorService. 

What about using IndexSearcher(ParallelReader)?

>>Regarding optimization?
I have sharded to multiple small indexes (in a single system). This helps to do 
faster indexing. I have updates every couple of minutes and the updates will go 
in latest shard. All shards will be optimized per day. If lucene performs well 
in searching multiple segment then i don't need to go for shards. I could very 
well use single index and don't optimize it. Whether it will impact search? 
Previous releases perform better in optimized indexes. What about 3.5.0?

Regards
Ganesh

You will need to rebuild if you switch to using NumericField.

The deprecation warning in the javadocs says "Please pass an
ExecutorService to IndexSearcher, instead" so I'd do that.

No.
