ColdFusion 9 and Solr: MultiValued fields vs. Tokenized

0
0

I was indexing a new collection yesterday and kept getting out of memory errors from the JVM (in truth, I don’t know if they were from JRun or from whatever JVM Solr was running in). Apparently either CF didn’t like the huge array I was generating, or Solr didn’t like me trying to cram it into a multiValued field of type slong. I decided to try something different – I created a space-delimited list of terms instead (they were all numbers, so no need to worry about phrases or anything like that). That worked great.

According to this question/answer thread on StackOverflow, there should not be a difference in results if that field is used for filtering. There may be a difference in scoring, but as I was only using the field for filtering anyway, that is not a concern.
