(d) What if users mistakenly think they have the correct page?

(e) Can some pages never be found?

(f) What should it do with common words that are independent of the help page?

(g) What about words that affect the meaning, such as “not”?

(h) How should it handle words it has never seen before?

(i) How can new help pages be incorporated?
