Smart Indexing for Better performance and functionality ??

[Yerraguntla <ra...@yahoo.com>]

Hi,
  I have the following use case. I could implement the solution but
performance is affected. I need some smart ways of doing this.
Use Case :
Incoming data has two fields which have values like 'WAL MART STORES INC' 
and 'wal-mart-stores-inc'.  
Users can search the data either in 'walmart'  'wal mart' or 'wal-mart' 
also partially on any part of the name from the start of word like 'wal',
'walm' 'wal m'  etc .   I could get the solution  by using two indexes, one
as text field for the first field (wal mart ) column and sub word 
wal-mart-stores (with WordDelimiterFilterFactory filter).  

Is there a smart way of doing or any other techniques to boost the
performance? I need to use them for a high traffic application where the
response requirements are around 50 milli seconds.
I have some control on modifying the incoming data and data set is around
100K records.

Can someone suggest better ways of implementing. I can provide more
information the tokens and filters I am using.

Thanks
Ravi
