Hello,

According to [https://github.com/elastic/elasticsearch/issues/31615](https://github.com/elastic/elasticsearch/issues/31615) we can sort by cosine similarity of vectors. But how can we filter by vector values?

For example I want to filter all docs that index number 10 in the vector is less than X number. In other words filter to the docs where my\_vector\_field[10] \< X.

How can this be done?  
Thanks,  
Sep

Hello,  
filtering by individual values is not supported. We have decided not to support sorting as well.  
Currently vectors can be used only in script\_score query using predefined [vector functions](https://www.elastic.co/guide/en/elasticsearch/reference/master/query-dsl-script-score-query.html#vector-functions).  
However, if you think that accessing individual fields is a valid use case, please [submit a new issue](https://github.com/elastic/elasticsearch/issues) describing your use case in more detail.

Ok cool. Thanks for responding. I will submit a new issue.
