The asterisk (*) wildcard represents a string of characters. for example 'b*t' finds bit, boat, and burnt
<(text): Finds string that starts with text, for example '<(per)' finds person and percent
(text)>: Finds string that ends with text: (per)> finds viper, deeper
[aei]: Finds any one of specified characters aei, for example s[aei]t finds sat, set, and sit
[m-z]: Finds characters in range m-z, for example [a-f]it finds fit, bit
[!m-z]: Finds any characters except those in range m-z: [!a-f]ield finds yield
{n}: Finds n instances of the last character, for example sho{2}t finds shoot, boot but not shot
{n,}: Finds at least n instances of the last character, for example sho{1,}t finds shot and shoot
{n,m}: Finds n to m instances of the last character, for example 3{1,4} finds 3, 33, 333, and 3333
