Re: Returning documents using multi-valued field
Thanks for you answer James :) For guys who would meet up with this problem, http://markmail.org/thread/xce4qyzs5367yplo also speaks about this, and reaches James' conclusion too.

This example assumes that your positionIncrementGap is set to 100 (the default I think) or greater.

Because the multi-valued fields are implemented under-the-covers by simply increasing the position of the next occurrence by the positionIncrementGap value, this will effectively prevent Lucene/Solr from matching across occurences. The downside to this workaround is that wildcards are not permitted in phrase searches. So if you need wildcard support also, then you're out of luck.

RE: Returning documents using multi-valued field
This is a limitation of Lucene/Solr in that there is no way to tell it to not match across mutli-valued field occurences. A workaround is to convert your query to a phrase and add a slop factor less than your posititonIncrementGap. ex: q=alice trudy~99 ... This example assumes that your positionIncrementGap is set to 100 (the default I think) or greater.
