您如何用Lucene找到一个短语？

Question

I hope the way I worded my question is correct, though I could be mistaken. Basically, I have an index with term vectors, positions, and offsets, and I want to be able to do the following: when I see the word "do", check to see if the next word is "you". If so, treat those two words as one phrase for the purposes of scoring. I'm doing this to avoid splitting up words that are commonly used together anyway. Instead of my list of words sorted by score looking like this,

do 
want
you
come
to

I'd like to see something more like this

do you
want
come
to

Answer 1

One workaround would be index both by word and by phrase, so your scoring list would be:

do you
want
come
to
do
you

If you then applied a boost to your phrases during indexing, you would be closer to your goal. But that depends on whether matching phrases should always rank higher than their individual words.
