Indexing 1000 documents/sec in Lucene is quite common, so even taking
into account large documents, 20 seconds sounds like quite a bit.
Shruthi: I had attached the code snippet in previous mail. Do you suspect a foul play there?

So it is not possible for a client to perform a broad phrase search to
start with. And it sounds like your DB-queries are all simple matching?
No complex joins and such? If so, this calls even more for a full
Lucene-index solution, which handles all aspect of the search process.
Shruthi: We call a DB stored procedure to get us the result set for working with..
We will be using highlighter API and  I don’t think Memory  index can be used with highlighter.
