Hi,  
I'm trying to delete one part of documents in an index by using regexp api but I can't.

The command is as follows.  
curl -XDELETE '[http://localhost:9200/index/type/\_query](http://localhost:9200/index/type/_query)' -d '{"query":{"regexp":{"\_id":"#document\_tag"}}}'

I use ES ver 1.7

I wonder if "\_query" is not available.  
Is there way to delete?

Thank You and Best Regards.
