Why admin page Search terms redirect to login?

Question

I'm using Magento 2.3 with ElasticSearch 6, I have 20k different searches per day.

I can see the top search terms in my Dashboard, but when I access the page Marketing > SEO & Search > Search Terms I'm redirected to the login page.

MySQL Query

How could I solve it?

Answer 1

The issue is the amount of data processed, you can improve the queries limits to return just the top results or you can apply these changed below via path or module to eliminate the counting of search terms.
