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' -d '
  {
   "query": {
      "bool": {
         "filter": {
            "term": { "status": "pending" }
         }
      }
   }
  }'
