Hi, I'm testing Elasticsearch as replacement to our current MongoDB implementation for storing and searching information. The application I'm working on has a Django frontend that query the information, and an engine built with Java. I have almost no experience working with Java, so I'm having some trouble to figure out how to store objects that have other objects as attributes. As you can see in here (1), I'm creating an user object with the information I need to store, and then I set this user as a content attribute. I know I'm doing something wrong because the document gets stored without the user information. In the log files, the user entry is sent as string ('user': {'type': 'string'}) . I thought to use a Map to store those fields I need from the user object, but I don't know if that is the Java way or even a nice way to doit. Could someone throw me a line here?

When you build the json, you need to have another "startObject" and "endObject" to wrap the json you construct (startObject == {, endObject == }).

Shay, Thanks for the response, but sadly I didn't got it working. I don't understand where should I put the extra startObject and endObjects calls. The user object is already created with startObject and endObject. If I call them when adding the user object to the content one I got an exception. Could you please be a little more specific, and perhaps with the two or three lines that will do what you said ? ... I'm really new with Java and I'm still struggling with language issues :S Thanks.

Sorry, I got confused by your code a bit. I commented with something that should work (the user aspect). I also added setId just so you can more easily fetch it by id (if you test it), nad actionGet() at the end of the index to wait for the index operation to finish (execute is async).

Martin, Hope you bit the bullet sometime for Java but you can probably avoid using it - at least to start/evaluate. I believe the ElastiSearc Head plugin only uses JavaScript to interact with ES. You might be able to do JS call replacements under Django.This might not be your long term solution but could let you see what ES can do. I also believe there are some JS clients for ES out there - though not sure if any are current/blessed. --Mike On Wed, Dec 7, 2011 at 10:43 AM, [marrese@gmail.com](mailto:marrese@gmail.com) [marrese@gmail.com](mailto:marrese@gmail.com)wrote: > Shay, > > Thanks for the response, but sadly I didn't got it working. > > I don't understand where should I put the extra startObject and endObjects > calls.

Mike, I got it working with what Shay said, so I can test ES using the same app we have right know, just with another storage.
