Hi

I have an index with keywords associated to a category. My goal is to be able to use these keywords for \_termvector.  
For example

```
KEYWORD | CATEGORY
---------------------
apple | fruit
banana | fruit
dog | animal
cat | animal
mouse | animal

```

I'd like to only get term of \_termvector using my KEYWORDS. Is that possible?

And even better if I could also have the category associated to a keyword in the \_termvector response that would be fantastic. Like a sub aggregation. If not possible, I always send an new request to ES server, it's not a big deal.

Thanks

If I understand correctly what you are asking for is a feature called terms filtering. We have something [like that](https://www.elastic.co/guide/en/elasticsearch/reference/master/docs-termvectors.html#_terms_filtering) in the dev version of ES, but it won't do what you'd like, until we add scripting. Right now it only filters terms based on their tf-idf scores. Concerning the sub-aggregation, I would think that you'd have to perform a new request each time. Hope this helps.
