Root Cause

Search query failed across all shards. Malformed query DSL, field type mismatch, or corrupt shard data.

generic

Workarounds

  1. 92% success Check root cause in the nested 'caused_by' field of the error response 
    The top-level message is generic; look at response.error.root_cause[0].reason for specifics

    Sources: https://www.elastic.co/guide/en/elasticsearch/reference/current/

  2. 88% success Validate query against mapping: ensure field names and types match 
    GET /my_index/_mapping  # then verify field types match your query expectations
  3. 85% success Use _validate/query API to debug query syntax 
    GET /my_index/_validate/query?explain=true { 'query': { ... } }

Dead Ends

Common approaches that don't work:

  1. Retry the same query assuming transient failure 75% fail

    If query syntax is wrong, retrying produces the same error every time. Check the root cause first.

  2. Delete and reindex to fix corrupt shard data 70% fail

    Reindexing is expensive and causes downtime. Most search failures are query issues, not data corruption.
