Hi there,

I have a question concerning the decompounding of the search term.

Use case:

- Search is a multi match search on "name" and "category"
- cross\_fields is used: each of the search terms need to be in one of the  
searched fields
- There is a product named "holzspiralbohrer"
- There is a product named "bohrer" in the category "holz"

-User is looking for "holzspiralbohrer" but doesn't know the exact  
terminology and types in the search term "holzbohrer"

In order to deliver results for "holzbohrer" I wanted to decompound the  
search term into "holz" and "bohrer".

To deliver the proper result, I would need to define something like this  
rule:

IF a search word gets decompounded ("holzbohrer" -\> "holz" "bohrer")  
THEN the decompounded parts should BOTH match in ONE field

In the stated example:  
-"holzspiralbohrer" should be in the search results  
-"bohrer" in the category "holz" shouldn't be

Is there any way of realizing this?

Many thanks in advance!

Best regards,  
Bernhardt
