Matching

To match a group of characters, surround the characters with parenthesis. For example:

(PINCH VALVE)

Will find a match wherever PINCH VALVE appears in a Component Class, such as:

PISTON ACTUATED PINCH VALVE

PINCH VALVE

To exactly match a literal in a regular expression ensure that the expression begins with the ^ character and ends with the $ character. For example:

^(PINCH VALVE)$

This will match PINCH VALVE but will not match PISTON ACTUATED PINCH VALVE.
