Ok,

You are talking about branch limit impact on search.

The search query is composed with "branch" code.
This code is used by Zebra throw CCL language.
Look at "etc/zebradb/ccl.properties", you may find :

    homebranch 1=homebranch
    branch homebranch
   holdingbranch 1=8012

You can see that "branch" is not a real index, "homebranch" and "holdingbranch" are.
Actually, "branch" is transformed into "homebranch" before Zebra searching.
So you sould solve your problem by changing this :
  
   branch holdingbranch

Be carfull, I don't know if it modifies other behaviours.

Regards,
