MIDReturns a segment of a string.
MID(string, starting_at, extract_length)
string – The string to extract a segment from.
starting_at – The index from the left of string from which to begin extracting. The first character in string has the index 1.
extract_length – The length of the segment to extract.
If the end of string is reached before extract_length characters are encountered, MID returns the characters from starting_at to the end of string.
To return the contents from starting_at to the end of string, use LEN to calculate the length of the string that will be returned rather than simply specifying a large number for extract_length.
To return the contents of string beginning with a particular character or sub-string, use SEARCH to locate the index of the desired point.

SEARCH: Returns the position at which a string is first found within text, ignoring case.
RIGHT: Returns a substring from the end of a specified string.
LEFT: Returns a substring from the beginning of a specified string.
