Tom: The output is numbing, but add &debug=true to your query and you'll see exactly what contributed to the score and why. Otherwise you're flying blind. Obviously something's trumping your boosting, but you can't pin down what without the numbers.
You can get an overall sense of what's happening if you return "score" as a an additional field, but that just gives you the result, now how it was calculated. However, if you notice your boosting has changed the scores in the right direction but just not enough it's an indication that bigger boosts may help. And do note that boosting _influences_ the score, it'll never guarantee an absolute ordering where "all titles that have the content will appear before any doc where the terms appear in the content". It'll also be easier to read if you output it structured, see: https://wiki.apache.org/solr/CommonQueryParameters#debug.explain.structured Best, Erick On Fri, Jan 13, 2017 at 7:10 AM, Tom Chiverton <t...@extravision.com> wrote: > I have a few hundred documents with title and content fields. > > I want a match in title to trump matches in content.
