Re: Elastic Search MLT API, how to use fields with weights.
I'd like to add to this that mlt API is the same as a boolean query DSL made of multiple more like this field clauses, where each field is set to the content of the field of the queried document.

Re: Elastic Search MLT API, how to use fields with weights.
I do not believe you can boost individual fields/terms separately in a MLT query. Your best bet is to probably run a bool query of multiple MLT queries each with a different field and boost, but you'll need to first extract the MLT text before you can do this. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Elastic Search MLT API, how to use fields with weights.
Hi, I want to use ElasticSearch MLT API, to find a set of documents similar to a document in my index. Since, I do not have "like_text" and do not want to make an extra request for retrieving "like text", I am using MLT API with document Id. The problem is that in our schema some fields weight more than other. For example, keywords_1 has double weight than keywords_2. Let us say I want to calculate "more like this" on these two fields, How can I do that? I have already tried using mlt_fields=keywords_1^2,keywords_2 but it is not working as it is expected. On empirical testing it appears that it is treating both fields as equal. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
