Hi there,

I’ve just started using aaf for searching and it’s running well apart  
from one error I received:

A ThreadError occurred in person#search:

`reindex\_model’

```
.....

```

Has anybody else had this before? Any ideas what could have caused it?  
It’s only happened once. I’m using ferret 0.11.4 and aaf trunk.

Cheers,  
-Jonathan.

Interesting. It might be because you ran your first search without  
having an index, so aaf triggered an automatic rebuild. Possible that  
this scenario hasn’t occured in my testing with the DRb server yet. I’ll  
try to reproduce this.
