Boolean Logic (Order of operations) A and B or C

Question

I am creating a "Basic Search" bar that users can type in terms. I am unsure of the order of operations for boolean logic.

If someone types terms(With no quotes):

A and B or C

What is the correct way to treat this?

(A and B) or (C)

OR

(A) and (B or C)

Solution 1

Wikipedia to the rescue, this should help:

From the looks of things, it would appear that AND takes precedence over OR in most languages.

Solution 2

Based on Quetzalcoatl's response, the correct answer for the OP question is:

(A and B) or C

That's the equivalent for "A and B or C"

Although Quetzalcoatl's link (http://en.wikipedia.org/wiki/Order_of_operations#Programming_languages) speaks about programming languages (as this site does), a more common precedence is specified for general logic in wikipedia:

The OP is not asking about the meanings of AND and OR, but their relative precedence.
