Elasticsearch - set max_clause_count

Question

I have a pretty big terms query in elasticsearch, so I get too_many_clauses: maxClauseCount is set to 1024

I tried increasing it in the elasticsearch.yml by

index:
query:
bool:
max_clause_count: 10240

and via

curl -XPUT "http://localhost:9200/plastic/_settings" -d '{ "index" : { "max_clause_count" : 10000 } }'

but nothing worked. My index is named plastic.

Answer 1

In Elasticsearch 5, index.query.bool.max_clause_count has been deprecated/removed.

Insert in your elasticsearch.yml file indices.query.bool.max_clause_count : n instead (where n - new supported number of clauses).
