Hi,

i'm currently thinking if i could write a has\_child filter differently to  
performe a faster search.

I want all products (parents) with the term "printer" and which have set  
the field "Client3.Type" to "K".

Currently i'm executing this query. But i think this way elasticsearch is  
first searching for the query and then filtering the results. I would  
preffere first to filter and then query the matching documents.

{

- index: "columns",
- type: "mainarticle",
- body:  
{
  - query:  
{
    - has\_child:  
{
      - type: "product",
      - query:  
{
        - filtered:  
{
          - query:  
{
            - multi\_match:  
{
              - query: "printer",
              - fields:  
[
                - "Title",
                - "Description"  
]  
}  
},

          - filter:  
{
            - 
## and: [
{  
- term:  
{  
- Client3.Type: "K"  
}  
}  
]  
}  
}  
}  
}  
}  
}

}
