Find & Select Formatting

This  feature enables you to  find and select text in a Google Doc according to its formatting

While Google Docs already has a built-in feature for selecting formatted text, Multi Find & Replace gives you more control:
1. You can find formatting in a selection of a large document.
2. You can do a more general search. For example, you can find and select text based on only one property, eg bold, or italic. But the built in function always matches every font property, so you can't just search for all bold text etc.
