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
