Hi Alexey,
Thank you for your suggestion! My understanding of Similarity, though,
is that this would affect the entire index, whereas I need something
that is field-configurable. Looking at Similarity.tf(), it seems to be
independent of the field (and unaware of it). I don't necessarily want

apparently independent features.
This relates to the index format, and is more for performance/size
benefits when they are not needed. In the index, it's
Though it would be possible to calculate a binary tf, where the score
is 1 if there are one or more occurances of the term. --wunder

Hi Yonik,
Thank you for the explanation. If the primary goal was to save index
space for a very specific subclass of fields, the implementation
certainly makes more sense. I wonder, though, if it could also make
sense to support a query-time only boolean to optionally disable TF
Hi Yonik,
For my particular needs, IDF considerations are fine and helpful; if a
user is requesting a rare term/phrase, increasing the score based on
that makes sense as the match has higher confidence. I simply need to
compensate for title and category type fields that may contain redundant

Hi Aaron,
You can overwrite default Lucene Similarity and disable tf and
lengthNorm factors in scoring formula ( see
http://lucene.apache.org/java/2_4_1/api/org/apache/lucene/search/Similarity.html
and http://lucene.apache.org/java/2_4_1/api/index.html )
You need to
1) compile the following
Just FYI - you can put Solr plugins in solr-home/lib as JAR files
rather than messing with solr.war
