- Searching for a group of words finds posts that have those words, in any order. Adding quotes around them finds those words as an exact phrase.
- Searching for alph* finds any words beginning "alph" (ie, "*" is a wildcard). This is super-useful for searching resources, as some of the titles lost their spacing, and haven't been fixed yet.
- Searching ignores punctuation marks, treating the characters before and after the punctuation as separate words.
