Subject RE: Wildcard searches????

Hi Ted and thanks for all your efforts. 
Listen im a little bit lost here trying to understand what you are trying to tell me :-)

1. I Store my useragents in a field that is tokenized.
2. Then when I search, you are saying that I should "scan" down the matches via a SOLR function,
or what?
Are you referring to these functions in SOLR?

Sorry for not grasping immmediatley!

Regards Niclas

Tokenize your user agent strings, then store the tokenized form separately
from the wild card.  At retrieval time, scan down the matches and apply the
wildcard from each document to your original query.  The SOLR function query
might be useful for this as would be a custom hit collector.
