I’m testing the following regex: 

(?i)(\s|\W|)(fire|fire-type)(\s|\W)

I have 2 problems:

1º Case (SOLVED) has only one word without spaces at the beginning or at the end my regex does not take. Ex:

fire

2nd In my group I have a fire-type but the regex only takes the word fire and igonara the -type. Does anyone know how I can solve these 2 cases?

  • What is the purpose of Regex? Is to find the words in a text fire and fire-type?

Usually in regular expressions the Hyphen - is a sequence indicator, for example, rather than writing [abcdefgh], we write, [a-h]. Or capitalize and minuscule with, [a-hA-H].

This way the Hyphen is character used to define sequences in regular expressions, if you want to locate a text with the hyphen we should warn the regex that they should be understood as literal preceding them with an escape signal \ (backslash), below some commonly used examples: 

\- (faz a busca pelo "-")
\] (faz a busca pelo "]")
\\ (faz a busca pelo "\")
