Different Elasticsearch results for the same query

Question

I\'ve setup Elasticsearch with 1 cluster á 4 nodes. Number of shards per index: 1; Number of replicas per index: 3

When I call a simple query like the following one

Answer 1

This is because you don't have specified sort order and size. So every time you query you get random first 10 records as default size for result set by elasticsearch server is 10.

You can add sorting in following way with curl,

curl -XPOST 'localhost:9200/_search' -d '{
 "query" : {
   ...
  },
   "sort" : [
     {"price" : {"order" : "asc", "mode" : "avg"}}
   ]
}'

Check here for for more info specially from and size with sort which is most mostly used for pagination.

update:

Though default sort is score DESC sometime it not works when records don't have relevant _score, as per http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/_sorting.html#_sorting
