Here i have created a gist example. I have created a indices with a single field named "message". In that indices, I have 10 documents with same message string, while searching on this indices i am getting different score values for resulting documents. Gist Example Here...... curl -XPUT '[http://192.168.0.141:9200/dbtest123](http://192.168.0.141:9200/dbtest123)' curl -XPUT '[http://192.168.0.141:9200/dbtest123/meta/\_mapping](http://192.168.0.141:9200/dbtest123/meta/_mapping)' -d '{"datatable" : { "properties" : { "message" : {"type" : "string", "store" : "yes"} } } }' curl -XPUT '[http://192.168.0.141:9200/dbtest123/meta/1](http://192.168.0.141:9200/dbtest123/meta/1)' -d '{"message" :"trying out Elastic Search It takes the snapshot while working on group of documents, Based on the snapshot, it will do update process or other task"}' curl -XPUT '[http://192.168.0.141:9200/dbtest123/meta/2](http://192.168.0.141:9200/dbtest123/meta/2)' -d '{"message" : "trying out Elastic Search It takes the snapshot while working on group of documents, Based on the snapshot, it will do update process or other task"}' curl -XPUT '[http://192.168.0.141:9200/dbtest123/meta/3](http://192.168.0.141:9200/dbtest123/meta/3)' -d '{"message" :"trying out Elastic Search It takes the snapshot while working on group of documents, Based on the snapshot, it will do update process or other task" }' .... .... .... up to 10 documents.... curl -XGET '[http://192.168.0.141:9200/dbtest123/meta/\_search](http://192.168.0.141:9200/dbtest123/meta/_search)' -d '{"query":{"term" : { "message" : "search" }}}' {"took":0,"timed\_out":false,"\_shards":{"total":5,"successful": 5,"failed":0},"hits":{"total":10,"max\_score":0.15581955,"hits": [{"\_index":"db123","\_type":"meta","\_id":"3","\_score":0.15581955, "\_source" : { "message" : "trying out Elastic Search It takes the snapshot while working on group of documents, Based on the snapshot, it will do update process or other task"}}, {"\_index":"db123","\_type":"meta","\_id":"8","\_score":0.15581955, "\_source" : { "message" : "trying out Elastic Search It takes the snapshot while working on group of documents, Based on the snapshot, it will do update process or other task"}}, {"\_index":"db123","\_type":"meta","\_id":"10","\_score":0.15581955, "\_source" : { "message" : "trying out Elastic Search It takes the snapshot while working on group of documents, Based on the snapshot, it will do update process or other task"}},{"\_index":"db123","\_type":" meta","\_id":"4","\_score":0.13005449, "\_source" : { "message" : "trying out Elastic Search It takes the snapshot while working on group of documents, Based on the snapshot, it will do update process or other task"}},{"\_index":"db123","\_type":"meta","\_id":"9","\_score": 0.13005449, "\_source" : { "message" : "trying out Elastic Search It takes the snapshot while working on group of documents, Based on the snapshot, it will do update process or other task"}}, {"\_index":"db123","\_type":"meta","\_id":"1","\_score":0.13005449, "\_source" : { "message" : "trying out Elastic Search It takes the snapshot while working on group of documents, Based on the snapshot, it will do update process or other task"}}, {"\_index":"db123","\_type":"meta","\_id":"6","\_score":0.13005449, "\_source" : { "message" : "trying out Elastic Search It takes the snapshot while working on group of documents, Based on the snapshot, it will do update process or other task"}}, {"\_index":"db123","\_type":"meta","\_id":"2","\_score":0.13005449, "\_source" : { "message" : "trying out Elastic Search It takes the snapshot while working on group of documents, Based on the snapshot, it will do update process or other task"}}, {"\_index":"db123","\_type":"meta","\_id":"7","\_score":0.13005449, "\_source" : { "message" : "trying out Elastic Search It takes the snapshot while working on group of documents, Based on the snapshot, it will do update process or other task"}}, {"\_index":"db123","\_type":"meta","\_id":"5","\_score":0.067124054, "\_source" : { "message" : "trying out Elastic Search It takes the snapshot while working on group of documents, Based on the snapshot, it will do update process or other task"}}]}}. Questions: 1. Why does the score varying for same content? 2. How does the score value calculated in Elastic Search...? 3. If i have a Boolean query for multiple field, Can we mention a specific field for score calculation for full query....? ---

Your docs are stored in different shards, so each shard has a local idea of how important each term is - it only knows about docs that live in its own shard. This is likely to be approximately right, but in certain cases (like your example) will be slightly inaccurate. If you add the parameter search\_type=dfs\_query\_then\_fetch this will retrieve the scores for the relevant terms from all shards first, calculate the real global value, then score correctly. However, this obviously doesn't perform quite as well as the default "query\_then\_fetch". Try: curl -XGET '[http://localhost:9200/dbtest123/meta/\_search?pretty=1&search\_type=dfs\_query\_then\_fetch](http://localhost:9200/dbtest123/meta/_search?pretty=1&search_type=dfs_query_then_fetch)' -d ' {"query":{"term" : { "message" : "search" }}}' clint ---
