We have a webmailer where experienced users are able to create 
filterrules. They can can choose from a lot of predefined headerlines 
and insert text to find. After that they choose a respective action.
To cover all cases we had a choosable option "complete header" to find a 
string in every headerline without knowing the specific line. This is 
done easily in procmail:

:0 H
* ^*searchstring

i agree that an option like this is needless and it was a mistake to 
offer it.
If this is not achievable in sieve, we have to remove this 
search-option. May be we replace by a kind of custom-headerline.
