I'm using scripts to implement some custom score function like:

```
∑is_ge_1(_index['FIELD']['TERM'].tf()) / my_query.termvectors('ANALYZER').size()
where TERM is one of my_query.termvectors(), and FIELD can be passed from script params.

```

I'm able to get `_index['FIELD']['TERM'].tf()` according to the [docs](https://www.elastic.co/guide/en/elasticsearch/reference/2.3/modules-advanced-scripting.html).

But how can I get the whole query term vectors just like `_analyzer` API?  
I've googled this before but didn't get something useful. Only lucene v3.5 has QueryTermVector API.  
Or if there's some other better approaches to implement this?

Thank you in advance.
