As you know I developed another simplified query language, which is
converted into the full CQP by regular expressions only (the simplified
language is simple by its nature).

In Forli we agreed on merging the two versions using the following
guidelines:
     1. a query term X on its own corresponds to [word="X"]
     2. a query term X followed (preceded?) by # corresponds to
        [lemma="X"]
     3. there can be conjunctions, disjunctions and standard regular
        expressions in query terms, which are simply sent unchanged to
        the output
     4. a query term X followed by /Y corresponds to [word="X"&pos="Y"]
     5. /Y on its own corresponds to [pos="Y"]
     6. a sequence of query terms separated by spaces corresponds to a
        sequence of corresponding CQP expressions
     7. symbol .. (two dots on their own) corresponds to a gap (I think
        we discussed the possibility of specifying the length of the
        gap, but I'm not sure about the syntax proposed)
     8. there's an option for specifying the order of constituents; in
        my current implementation this is +nX +mY which corresponds to
        MU(meet "X" "Y" -n m), but again I can't remember the final
        details we agreed on

I think this is all we need for CEQL and this syntax can be easily
implemented by regular expressions.  Anything beyond this set has to be
expressed in the full CQP syntax.
