Wildcard Operators
The * operator replaces zero or more characters, so searching for w*ess would match “wilderness”, “witness”, “WordPress” and also “wess”.
The ? operator matches exactly one character, so searching for gr?y would match “grey” or “gray”, but not “gravy” or “groovy”.
Boolean Searches
Relevanssi uses + and – for the operators: cats -dogs and cats +kittens.
If you prefer instead to use the verbal AND and NOT operators, those can be used too.
Phrase Searches
Put phrase in quotation marks, e.g., “just as complicit”.
