(I hope this post didn't sent twice..) Hello, I would like to migrate an app I wrote using Compass to work with ElasticSearch (the Java API). I did some searches and experiments, but failed to find the answers, so can you point me to relevant docs to examples? My questions are as follow: 1. How do I index complex object (object that contain other objects ) using the Java API? There are few words on that in the REST API, but when I tried to work something with the Java API I got exceptions... 2. How can I declare what object properties are searchable and what are not? It it very easy in Compass with the annotations, didn't found the relative config in the Java API.. 3. Is the Java API allow bulk inserts (transactional)? Thanks for any help! ---

There is a bulk API, but its not transactional. In upcoming 0.15 (master) there is support for versioning (optimistic concurrency control in DB lang). > Thanks for any help! ---

Hello, I'm actually implementing an OSEM for Elasticsearch, It's in early phase, but you will be able to use it like you used Compass before (annotation based). I created annotation almost like in compass (even copied some of them as is) to define indexing configuration and you will be able to use JAXB annotation for serialization specific configuration (used by jackson).

This is sounds really nice, can you share your work? Thanks.

Wow.. Alois I've just read your message, I've been peeking around the compass and Elasticsearch thinking to implement the OSEM as well, we might be able to work together on this if you want to. What do you think?

I'll open-source it as soon as possible, I already had a chat with kimchy to be sure to start in the good direction. I'm doing it a job and just want to finish the basis before sharing, but unfortunately I wasn't able to work on it last week. I hope to do it before end of the month, I'll keep in touch guys !! Would be really happy to have some help on this 🙂 A+ Alois Cochard ---

Alois, I'm eager to start working on that. Looking forward to hearing from you. Let me know if you want me to start checking on something.. I guess we can discuss it via PM I'm still on the reading code phase but ready to start hacking the code. Hopefully we can do a pull request soon Mauricio On Feb 2, 2:22 am, Alois Cochard [alois.coch...@gmail.com](mailto:alois.coch...@gmail.com) wrote: > I'll open-source it as soon as possible, > > I already had a chat with kimchy to be sure to start in the good direction. > I'm doing it a job and just want to finish the basis before sharing, but > unfortunately I wasn't able to work on it last week. > > I hope to do it before end of the month, I'll keep in touch guys !! > > Would be really happy to have some help on this 🙂 > > A+ > > ## Alois Cochard > > View this message in context:[http://elasticsearch-users.115913.n3.nabble.com/From-Compass-to-Elast](http://elasticsearch-users.115913.n3.nabble.com/From-Compass-to-Elast)... > Sent from the Elasticsearch Users mailing list archive at [Nabble.com](http://Nabble.com). ---

I've finished a working POC, took some times because I did it on my free time... Gonna fork ES and add new code before this week-end. I let you know when code is ready !
