Adjusting Apache Solr bias based on content length? I have a site using the Apache Solr Search Integration module with a short-form content type that is getting weighted too highly in the Solr index. I've tried adding "Bias" to the other content types and leaving the short-form content type set to Ignore, but even with other bias settings maximized the short pieces still rise to the top. Looking at the particular items that appear at the top, it seems to be that multiple instances of the search terms in a short piece cause it to rank higher.

According to the help on the bias settings page, "Any value except Ignore will increase the score of the given type in search results." Is that a limitation of the Solr module or of Solr itself? Ideally, I'd like to decrease the relevance of the short type. What are my options for doing that?
Under bias setting you should be able to reduce the priority of the fields. So reduce the priority of the fields that is not much important, and increase the priority of the fields that you would prefer for solar to prioritize.

The settings can be found on: admin/config/search/apachesolr/settings/solr/bias

0.1 is the lowest and 21.0 is the highest rating.
