I think you could do it this way: Add a new hash, that saves for every
term/document combination the positions of the term's occurences. Position
is relative to the other words, e.g.:
foo bar blah
foo is position1, bar is position 2, blah is position 3 etc.
Now if someone searches for "one two" you have a match if:
pos("one") == pos("two")-1 in a document. With this algorithm you can also
implement a NEAR operation.
