Subject Re: Indexing and Query time boosting together
Date Fri, 02 Aug 2013 12:04:05 GMT
Add &debug=all to your query, that'll show you exactly how the scores
are calculated. But the most obvious thing is that you're boosting
on the titleName field in your query, which for doc 123 does NOT
contain "phone" so I suspect the fact that "phone" is in the titleName
field for 122 is overriding the index-time boost, especially since "phone"
appears in both title and description for 122.
