Multi word searcher από ismorozs

Standard search utilities allow you to search strings in text only by one word.
This extension allows you to search strings using multiple words and deciding how long of a distance is tolerable between those words.
As well as allowing to have multiple searches highlighted at the same time, have them blinking for better visibility and jumping from one highlight to another.

How to use
Click the green plus sign to the right of the current input to create a new input for entering an additional substring.
Click the red minus sign to the left of the current input to remove it.
Set a number in a smaller input that will correspond to a maximum allowed distance in characters for searcing between two substrings.
