too many nested clauses


  • Frontend Error Dialog popups show something like: too_many_nested_clauses Query contains too many nested clauses; maxClauseCount is set to 1024

  • This may appear e.g. directly after logging into the fylr webfrontend.

  • This user cannot see records or pools that they should be allowed to see, according to rights management.


  • For the indexer (ElasticSearch or OpenSearch), allow more clauses per search.

  • This can lead to performance degradations and memory issues.

  • E.g. add to docker-compose.yml the one line about clauses: (default is 1024)

      - indices.query.bool.max_clause_count=4096
