[CWB] Any way to filter out some preceding tokens in a CQP query?

[Ray Wu]

Hi all,

CQP's zero-width assertions are quite handy when we want to filter out some tokens after a CQP query. A typical example is given in Stephen's "Inside the IMS Corpus Workbench" presentation to find clausal verb complement:
[pos="VB.*"] "that" [:pos!= "JJ.*| N.*":]

My question is: is there a way in CQP to limit the content BEFORE a CQP query? I guess that mechanism might be equally handy in other situations.

Thanks for any input.

Best
Ray









Best,
Ray
