I was wondering whether we could, while indexing, make a use of this by increasing the position counter by a large number, let's say 1000, whenever we encounter a sentence separator (Note, this is not trivial; not every '.' ends a sentence etc. etc. etc.). Thus, searching for
"income tax"~100 "tax gain"~100 "income tax gain"~100 income tax gain
would find "income tax gain" as usual, but would boost all texts where the phrases involved appear within sentence boundaries
This is exactly the sort of approach I was advocating in earlier messages. (Although I think you'd only need to increase the position counter by 101 for the first word in each sentence.) Herb Chong didn't seem to think this was appropriate, but I never understood why.
