[CWB] cqpWEB limitations

[Josep M. Fontana]

Hi,

We are trying to get as many of our users as possible to use the CQPweb 
interface because the learning curve us substantially less steep.

There are some students, however, that need to do some rather complex 
searches that are not possible with the Simple Query Language Syntax. 
Instead of creating an account for them in our server and giving them 
SSH access to an account, we prefer to encourage them to use the CQP 
syntax on the cqpWEB interface.

This seems to work well enough in many cases but every now and then they 
encounter some problems which we don't know how to deal with. The 
problem is that the only documentation about cqpWEB we have is the 
manual for the simple query language syntax and Andrew's article 
("CQPweb -- combining power, flexibility..."). Is there any new, more 
extense documentation?

For instance, some students are having problems extracting frequencies 
from searches that use the CQP syntax. Recently another student has 
reported that she gets the following error message when she tries a 
search which I can do without any problem via terminal.

--- error msg ---
A script was passed a badly-formed parameter set!

The content of the query was not specified!

... in file /srv/web/llocs/cqp/lib/concordance.inc.php line 137.

---- end error msg ---

Of course, it is possible that these are problems that have to do with 
our installation but I would like to know whether there is any 
documentation where we can find information about the limitations or 
problems that the web interface has with respect to regular CQP.

Thanks in advance.
