Two suggestions for MarkSubString function

[saeid2016]

Hello, I have two suggestions for MarkSubString function.

1. Edit the operation of rvmsoIgnorePunctuation option so that when we search for "Worlds" find "Worlds", "World's", "Wo'rlds", "Wor;lds" and etc.

2. Add an option to define any synonyms for any words and find that synonyms. For example when we search for "1" find "one".

As for the second suggestion, I think you can simply call the function twice, with '1' and 'one' parameter.
As for the first one, I'll think about it.
