No, I just looked for bugs in it and found several.
It is almost as you described:
the proximity operator is "..."
you can not control the distance
"..." is effectively an "and" with a high score when the
terms are near together and a lower score for higher
distances
term in "..." are effectively combined with "...",
thus: '"bear wine champagner"' is equivalent to
'bear ... wine ... champagner'
ZCatalog would interpret "FIDELITY ... MUTUAL FUNDS"
as "(FIDELITY ... MUTUAL) or FUNDS"
The nearest result what "sean" asked for, would
probably be 'FIDELITY ... "MUTUAL FUNDS"',
which is equivalent to 'FIDELITY ... (MUTUAL ... FUNDS)'.
I have not too much confidence in ZCatalog (yet ; this
may change now that Chris P is responsible for it).
I doubt, it will implement "A ... B ... C"
sensefully.
It is a big question, all together, whether a binary
operator is the correct choice for proximity.
