Query Choices

  • Avoid wild-card and regex queries
  • Using full-text and non-analyzed searches on the same field - use multi-fields
  • Return fields required only rather than all fields:
    curl 'localhost:9200/ordering/order/_search?pretty=true' -d '
    {
      "fields": ["planedOn"]
    }'
    
  • Use filter whenever possibly to suppress scoring:
    curl -XPOST 'localhost:9200/ordering/order/_search?pretty=true' -H 'content-type: application/json' -d '
    {
     "query": {
        "bool": {
           "filter": {
              "term": { "status": "pending" }
           }
        }
     }
    }'
