This adds term query capabilities for rank_features fields. term queries against rank_features are not scored in the typical way as regular fields. This is because the stored feature values take advantage of the term frequency storage mechanism, and thus regular BM25 does not work. Instead, a term query against a rank_features field is very similar to linear rank_feature query. If more complicated combinations of features and values are required, the rank_feature query should be used. |
