: Coming in a bit late but I would like a variant that is not a No-OP. : Think of something like title:searchstring^10 OR catch_all:searchstring : Of course I can always add the boosting at query time but it would make : life easier if I could define a default boost in the schema so that my : query could just be title:searchstring OR catch_all:searchstring : but still get the boost for the title field.
That would be a query time boost -- not an index time boost. An index time boost is a very specific concept that refers to increaseing the fieldNorm of a field in a specific document. What you are describing would be a query time boost, in which solr knows that certain query clauses should be worth more. You can already do esentailly this exact same thing using the dismax parser, but i suppose it would also be possible to modify the LuceneQParser so that it could take in configuration that would tell it to apply different default query boosts to different fields. -Hoss
