Erik Hatcher commented on SOLR-737:
-----------------------------------
Andrew - for one, you can increase the boolean clause limit (at the risk of a
less performant query). In solrconfig, adjust this:
<maxBooleanClauses>1024</maxBooleanClauses>
Also, there are many tricks that can be played to make wildcard querying more
efficient if you are willing to sacrifice index size and manage index analyzer
and query analyzer carefully. Have a look this topic in the [EMAIL PROTECTED]
archives. I did a lot of work once upon a time for a client that involved term
rotation during indexing and then morphing wildcard queries to have maximal
prefix for best efficiency.
As a thought experiment - consider what you'd do if you had to satisfy a
patrons request for "find me all books matching r*a* in the title" using a card
catalog system! :)
