Kapil Chhabra indicates on his blog that if you boost a value in a multivalued field during index time, the boosts are consolidated for every field, and the individual values are lost.
Here's the link: http://blog.kapilchhabra.com/2008/01/solr-index-time-boost-facts-2 This post is from 2008-01-20, but it still seems to be true in Solr 3.1. Has this behaviour been fixed in future versions of Solr, or are there plans to fix it? In general, when a user searches for a document, I'd like to arbitrarily weight each keyword for that document during index time. For example if they searched for "q=keywords:monkey", and got these documents: keywords: [ monkey, ape, chimp, garage ] keywords: [ monkey, cloud, food, door ] I'd like to have boosts recorded like this, at index time, based on keyword co-relevance: keywords: [ monkey:50, ape:50, chimp:50, garage:0.1 ] keywords: [ monkey:1, cloud:1, food:1, door:1 ] Since, in the first document, the word "monkey" is clearly related to "ape" and "chimp", but "garage" is not. Similarly in the second document, none of the keywords are really related to each other at all. I see a couple of potential solutions to this problem, in the absence of boosts for multivalued fields: 1. Turn keyword lists into strings, and use payloads: "monkey|50, ape|50, chimp|50, garage|0.1" 2. Use dynamic fields of the form: keyword_*: keyword_monkey, keyword_ape, ... and boost those fields. Are those solutions feasible, or are there better solutions to this problem? - Neil
