Word searches return a match on individual words, not the entire phrase.
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.
We recommend trying to use a longer, more detailed search phrase and you should get fewer matches.
