Hello,

I'm using elastic search in order to store information about search terms.  
My document structure:

- site
- search term
- date (year and month)
- data1
- data2

I have an index for each month.

For a given query with site and search term boolean search (substrings to include\exculde),  
I want to get the number of search terms per number of words (without duplications), for example:

- 5 search terms with 1 word
- 10 search terms with 2 words.
- total search terms: 15

I'm trying to use cardinality-aggregation (with precision\_threshold = 40,000) but getting inaccurate numbers. In a single query, I may aggregate data over 360,000 search terms.  
There is a way to get accurate result in my case?

Thanks,  
Kobi
