+            }
+        }
     });
 
 ## redis
 The find function does ignore the query argument and always fetches all items in the collection.
 
+## Elasticsearch >= 5.X
+Use the 'elasticsearch6' type for Elasticsearch versions 5.X and 6.X.
+
+The find queries are not mongoDb compatible as the rest of the implementations due to the uneeded overhead and complexity of converting between both formats.
+
+For find queries with elasticsearch6 use elasticsearch [native elastic Query DSL](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl.html);
+
+repository.find( onlyTheQueryClause, otherBodyOptions, callback);
+
+```javascript
+    repository.find(
+        {
+            range : {
+                age : {
+                    gte : 10,
+                    lte : 20
+                }
+            }
+        ),
+        {
+            from: 0,
+            size: 10,
+            sort: { age: 'asc' }
+        },
+        function(error, results) {
+        });
+```
+
+Additionaly for elasticsearch6 the number of shards, number of replicas, the refresh behaivour on index and the mappings on index create can be addtionaly defined to optimize performace.
+
+```javascript
+    var dummyRepo = repository.extend({
+        collectionName: 'dummy',
+        repositorySettings: {
+            elasticsearch6: {
+                refresh: 'wait_for', // optional, refresh behaviour on index, default is true ( ie. force index refresh ) https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-refresh.html                
+                waitForActiveShards: 2 // optional, defaults to 1 ( ie. wait only for primary ) https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-create-index.html#create-index-wait-for-active-shards
+                index: { // optional applied on index create, https://www.elastic.co/guide/en/elasticsearch/reference/6.x/indices-create-index.html
+                    settings : { // will be merged with the default ones,
+                        number_of_shards: 3, // optional defaults to 1,
+                        number_of_replicas: 1 // optional defaults to 0,
+                    },
+                    mappings : { // optiona will be merged with the default ones, 
+                        properties: { // specific properties to not be handled by dynamic mapper
+                            title: { 
+                                type: "text"
+                            }
