We have recently moved from AWS ES 5.x to 7.10. While performing search operation I go get the above error. In total my fields are between 2500 to 4000 for now. I know these values are not good, but this somehow worked on the old ES cluster.
I have already increased the value for
indices.query.bool.max_clause_count to 2048 for now . I see this is a common problem.
Can you guide me any documentation for the fix or increasing indices.query.bool.max_clause_count or reducing fields are the only solution?
