Basics of Regular Expressions
You can match a word by putting it between two brackets.
As example, this will only match the word "Dinosaur": (Dinosaur)
If you don't want to match something you will have to put a ?: before it.
As example, this will not match the word "Donkey": (?:Donkey)
You may also want to catch multiple options, for that we use a "Vertical bar" or also known as a "Pipe" between linux users.
As example, this will match if either "Cat" or "Dog" is present: (Cat|Dog)
To match anything of any length, use (?).
Character classes
To match a word, you put it between two brackets.
Example: (Banana)
Sometimes you have to use special characters but it may cause conflicts. In this case, you will have to use an escape character.
For example, this is a star that doesn't interfere with other matches \*.
