After googling "fuzzy logic" & finding out that it is multi-value, rather than two-value, logic, it occurs to me to wonder:
- is Google based on fuzzy logic? (like when it might ask "did you mean...")
- was A.E. van Vogt's "Null A" a use of an earlier expression of fuzzy logic?
just idle wonderings

Fuzzy logic is not about having multiple possibilities. It's about the granularity of said possibilities. Consider fuzzy logic as a way to score the wieght of a result and classify it into a generalization.
- FF0000 is red. Inversely, #110000 is also 'a little bit red'. Both results are correct, depending on what the question is.
If you ask what rgb value is red, the fuzzy logic could return #FF0000 (red) and #110000 (a little red). If you ask which is the most red, then it can make a definitive answer of #FF0000
Note that while you can classify the various levels of accuracy, in fuzzy logic the classifications are not exclusive of eachother.
Eg. < 1% = not < 19% = little bit < 39% = kind of < 59% = sort of < 79% = alot < 99% = mostly
- FF0000 can fall into all of those classifications, except 'not'
- 110000 only falls into the 'little bit' class
Google uses bayesian filtering. It builds heuristics of search terms in relation to the results that the searchers ultimately choose. Eg. if every person that searches for microsort, ends up going to msn.com, google can deduce that you probably mean microsoft. not microsort.
