Matching Search Terms?

[James Carman]

We have a requirement for our project where the user would like to be
able to paste a bunch of terms into a search box.  They want to
basically "or" together each line of the pasted text as a full-text
search query.  However, when the results come back, they'd like to
know which one of the lines matched the specific item returned.  Is
there an easy way to do that with Lucene?  I looked at the Hit API,
but nothing really jumped out at me.  I would think that's where I
should look.
