I am implementing a document boost at indexing time for the documents. I read
some posting that
seemed to indicate that omitNorm=false is needed to retain the document
boosting for retrieval.
After I did that, it looks like I am not able to get back the boost I
originally put in. Instead,
I get 1.25 as the score for all the documents retrieved.
Example:
Input
<doc boost="1.33">
<field name="uniq_id">3557_183970_10179</field>
<field name="login_name">user1</field>
<field name="show_all_flag">Y</field>
</doc>
Schema.xml
<fieldtype name="stringB" class="solr.StrField" sortMissingLast="true"
omitNorms="false"/>
<field name="show_all_flag" type="stringB" indexed="true"
stored="true"/>
Output for
(http://testing:12002/solr/select/?qt=dismax&q=Y&qf=show_all_flag&fl=score,login_name)
<doc>
<float name="score">1.25</float>
<str name="login_name">5webdesign</str>
</doc>
I am not quite sure how the score changed from 1.33 to 1.25. I am not quite
sure how this might have happened - I have modified the custom similarity
but I don't quite have an explanation of how the score changed.
Have you looked at the score explanation debug data? The document
boost is incorporated into the fieldNorm and so is modified by the
lengthNorm. Further, during query the term idf, queryNorm come into
play.
You shouldn't expect that the document boost will be returned as the
document score (although you should expect it to affect it).
