Can we please verify:
new mode: +a +b +c +d
just mean that you have to pre-append "+" to each term in the query string?
Query String = World Wide Web
AND Query String = +World +Wide +Web
So that the AND query string means that you would like to search all those
documents in which ALL the terms in the query appear?
Melissa.
