[CWB] What's possible via the CQPweb interface

[Josep M. Fontana]

Hi,

If the answer to this question is to be found in some specific section 
of some manual or documentation, please point me to it but I haven't 
been able to find it consulting the documentation that is available to me.

The question is simple. What are the exact limitations of the CQPWeb 
interface to use the full cqp syntax? In general I always recommend the 
CQPWeb interface to most of my undergraduate and to the new grad 
students because I find many are intimidated by the terminal (I work in 
the context of the humanities and except for very old people who still 
remember DOS, few people have experience using the command line in a 
terminal window).

This generally works well but every once in a while when I'm trying to 
show them something I need to use the full CQP syntax because this is 
what I am most familiar with and I can remember better. Most regular 
searches are OK but the other day, for instance, I tried to get the 
frequencies of the particular lemmas appearing in the last position of a 
particular search involving only reference to POS and I got an error 
message. Unless I did something wrong (although I checked and it worked 
with the terminal), this doesn't seem to be possible in the web interface.

I tried to use the 'frequency' option in the CQPWeb interface but I 
realized I didn't know how to use it properly. I know there are some 
wonderful videos but at that time I needed some written documentation to 
find information about what I needed to do and I wasn't able to find it. 
Is there any good user guide or reference manual in written form?

I totally understand that the goal of CQPWeb is not to replicate the 
functionality of the command line and that by definition there are going 
to be some restrictions in what you can do. But is there any 
documentation where all of this is made explicit? I have access to the 
paper Andrew wrote and to some some tutorials people have created but is 
there any other more complete manual out there with more detailed 
information about what is possible and what isn't?

Thanks a lot in advance and my apologies if I have ignored something 
that should be really obvious.
