In other words, if you search the Quotes section for, say, "I Love You", you'd get both these:
"Virginia Lewis: I really do like you. I like you a lot. And, I never want to hurt you. I think I love you."
"Sheriff Lucas Buck: I could never imagine myself in what you call "love"."
as valid matches, because they both include all three words "I", "Love" and
"You", regardless of their order.
Try using a longer, more detailed search phrase and you should get fewer matches.
