Hi, If I'm not wrong you cannot boost fields in _all field on query time. Querying the _all field should take in account the index-time boost, but for query-time boost you will need the field names you are searching in. You can set boost for a field at query time using "^": "title^5.0"
You can probably do query on ["title^5.0", "_all"] and don't set the boost in the mapping (index time) This way the matches in _all will have base boost of 1.0, but if there is match on "title" field you should get additional boost of 5.0 Regs Tihomir 08 август 2014, петък, 16:15:55 UTC+3, Mike Topper написа: > > Hello, > > sorry if this question is already explained in the docs but i tried to go > through all the boosting and custom scoring documentation and didn't find > what i was looking for. > > I'm trying to write a query that will give preference to certain fields > when doing a match query on "_all". so for example to be able to score > higher when the query matches the title and author fields than it would > when it matches on a subject field.
