Hi, I am getting the following NullPointerException while searching, I  
am using the master branch (rev 25eba4b6):

Hi Michael

I don't know if this has anything to do with your problem, but it looks  
like you're not passing UTF8-encoded text to Elasticsearch:

> [2011-04-14 15:44:38,756][DEBUG][action.search.type] [Calypso]  
> [19734] Failed to execute query phase

> [dsearch\_all\_3ae4][1]: query[(content\_text:"doku soap"  
> content\_text:fotos content\_text:brüder) content\_text:"tank

```
                            ^^

```

does it work if you don't include that term?

Thanks for the patch, I just tried it out and the exception is gone.

Although now I get another exception in the same context, I am using  
up to 50 connections at once using a single client:  
Could it be a concurrency problem?

Might be, the context is by default timed out (between the query and fetch phase) after 5 minutes, but I doubt its the case. Can you recreate it in a standalone testcase?

Hi, I haven't been able to recreate the issue. Thanks for the clarification.

Damn, was hoping you could :). Well, if it happens again, ping me. Had another look, and ran some of the stress tests I have and things worked well.
