Scite supports standard boolean search using "AND", "OR", "NOT".
Brackets "(" and ")" can be used for grouping and quotes "" can be used for exact matches of particular words or phrases.
Wildcard searches can be run on individual terms, using ? to replace a single character, for example "behavio?r" and * to replace zero or more characters, for example "lang*".
Fuzzy matching can be used by adding a tilde (~N) to the end of a term where N is the number of characters that can be different. Example: citations~2.
Proximity matching can be used by adding a tilde (~N) to the end of a set of word in quotes where N indicates how far two words can appear from each other. Example: "citation statements"~4.
