+This page lists some general tips and tricks provided by the community
+
+## Posting Elasticsearch queries from javascript
+
+Consider a scenario where you are using client side libraries like [elasticjs](https://github.com/fullscale/elastic.js)  
+but want security to be provided by server side business logic. Consider this example using `WebAPI`
+
+**NOTE** make sure dynamic scripting is turned off if you decide to open the full query DSL to the client!
+
+```cs
+    [RoutePrefix("api/Search")]
+    public class SearchController : ApiController
+    {
+        [ActionName("_search")]
+        public IHttpActionResult Post([FromBody]SearchDescriptor<dynamic> query)
+        {;
+            var client = new ElasticClient();
+    
+            //Your server side security goes here
+
+            var result = client.Search(q => query);
+            return Ok(result);
+        }
+    }
+```
+The fragments `[RoutePrefix("api/Search")]` and `[ActionName("_search")]` will let you change your elastic search Url 
+from `http://localhost:9200/_search` to `http://yourwebsite/api/Search/_search` and let things work as normal. 
+The fragment `[FromBody]SearchDescriptor<dynamic> query` will convert the JSON query into NEST SearchDescriptor. 
+The fragment `client.Search(q => query)` will execute the query.
