Yeah. Though, 20 seconds still sounds like crazy, not something that
I'd expect from that not terribly complex and demanding query. It's
hard to tell where exactly the bottleneck

But is there a reason for the searches to be that slow. I understand
that we have a pretty long list of synonyms (one word contains atleast
If there are twenty synonyms, then a one term query becomes a
twenty term query, and that means 20X more disk accesses.

Can you suggest some areas where we can start looking into this issue?

two general comments on this thread as a whole...
1) it's hard to compare the timing of a query with no synonyms and a query
with a lot of synonyms since the number of terms increases and (most
likely) the number of documents matched in increases as well.

Hi Otis,
I tested by taking out the newly added synonyms data and the query time
was back to normal ~125ms.
I will verify the debugQuery and update you with the results

Hi all,
I recently implemented query time synonyms in my application
and I am seeing drastic performance degradation.
The synonyms file is counts around 1000 words.
The average querytime without synonyms is around 125 ms
