I see your points. My current problem was I wanted to search for sequences
of finite verbs + gerund, but make sure that estar was not included as
finite verb form (by far the most frequent in my corpus).
But this was just an example, it was not derived from real needs. So
basically I'm good. The customization options you gave are good to know and
that's enough for me right now.
Thanks!
Marti
pd I guess it's unfair to think as a CQP speaker and act as a CQPWeb
natural user ;-)
