Hello,
I have a question about scoring when i use the dismax handler. I will give
some examples:
name category related
category
1. Chelsea best club ever Chelsea Sport
2. Chelsea Chelsea
Sport
When i search for "Chelsea" i want a higher score for number 2. I think it
is a better match on fieldlength.
I use the dismax and both records has the same score. I see some difference
in fieldNorm both still the score is the same. How can i fix this?
my config:
<requestHandler name="dismax" class="solr.SearchHandler" default="true">
<lst name="defaults">
<str name="defType">dismax</str>
<str name="qf">
name category related_category
</str>
</lst>
<str name="tie">1.0</str>
</requestHandler>
