Comment 7 for bug 1152863

I personally apologize for not reviewing the proposal earlier. I try to review everything I can as early as I can, but time is limited.

Could we perhaps drop support for lower-case versions of the operators, thus requiring upper-case, and then extend that support to all search interfaces? That would bring consistency to our advanced search syntax and avoid most of the copy-paste surprises that people would run into when they inadvertently include an operator, which are my primary concerns. And hopefully upper-case "OR" / "AND" / "NOT" would be considered teachable by the info lit people on your side.

It would also better match Google's operators in its advanced search syntax, and that tends to be a good thing:

* NOT: -prefix (which we already match)
* OR: OR
* AND: (ostensibly implicit, but "justin lise" provides much different results than "justin AND lise" -- and the results from the latter match '"justin" "lise"' , which is the new syntax from Google for "must include" that replaced the +prefix when they had to steal that for plus.google.com)
