You have different options here. You can give more boost at indexing time to the documents that have set the fields you want. For this to take effect you will have to reindex and set omitNorms="false" to the fields you are going to search. This same concept can be applied to boost single fields instead of whole document boost. Another option would be to use boosting queries at search time such as: bq=video:[* TO *]^100 (this gives more boost to the documents that have whatever value in video field).
The second one is much easy to play with as you don't have to reindex every time you change a value. On the other said you pay the performance penalty of running one extra query. -- View this message in context: http://lucene.472066.n3.nabble.com/Boost-documents-based-on-the-number-of-their-fields-tp3266875p3267628.html Sent from the Solr - User mailing list archive at Nabble.com.
