I wanted to follow up on this thread from yahoo groups. Thanks to Pawel and GaryB for their help, especially this link:
http://blogs.warwick.ac.uk/chrismay/entry/lucene_and_prefixqueries/which explains what counts as a lucene clause.
I wasn't able to really follow the explaination for modifying the search routine to reduce the number of clauses used in a query, but by simply bumping the maxClauseCount in the web.config file (add key="Lucene.Net.maxClauseCount" value = "2048"), I was able to search my 1500 nodes.
I am a bit concerned with just increasing the memory usage, especially since my content grows pretty quickly.
Won't this become an issue for the search on the this forum pretty quickly as well? I assume each post is a node, Niels, have you corrected for this in your search implementation?
