Hey,  
I want to look for documents who has field x **OR** field y.  
I can't use bool:should because i'm using a bool:filter in the same query..

my current query:

> GET /testing/\_search?size=200  
> {  
> "query": {  
> "bool": {  
> "filter":[  
> {"regexp": {  
> "look\_for\_regex.keyword": "some\_regex" }},  
> {"exists":{"field":"x"}}  
> ]  
> }  
> }  
> }

the current query only looks for field x, how should i filter the documents who has field x or y?

Hi,

You can have bool queries into another bool must or should, etc...  
So you can have a big bool with 2 should, with minumum should match = 1.  
1rst bool will contains your current bool query, the 2d should will contain the exist on the y field.
