I'm a librarian who loves anime, manga, and reading a wide variety of genres.
When searching in BookLikes, whether you use "&" or "and" matters. I figured this out when I tried to find posts on "Fire & Flood" by searching for "fire and flood." The posts I wanted only came up when I searched "fire & flood."
I kind of want to sit down and figure out all the quirks in BookLikes' searching, but it reminds me a little too much of what I do at work. Maybe later.
Things I know so far:
ETA: My second bullet point turns out to be the reason why "fire & flood" and "fire and flood" bring up different results. In the case of "fire & flood," I think "&" isn't being included in the search at all. "Fire and flood" treats "and" like a word, so "and" and "&" aren't seen as the same thing. I know that people don't always know how to use Boolean operators, but they're really useful to people who do. I'm kind of hoping BookLikes includes them in some kind of advanced search in the future. Another thing to add to my personal BookLikes wishlist...
