Thanks for your inquiry. In your case, we suggest you following solution.

  1. Please implement IReplacingCallback interface to find the specific word.
  2. In IReplacingCallback.Replacing, get the matched node using ReplacingArgs.MatchNode property. Please use Run.Font property to set the text formatting.

The code example shared in following article highlights the text. You can use the same code example to get the matched Run nodes and set font formatting.
How to Find and Highlight Text

In the code example shared in above article, please replace following foreach loop

foreach (Run run in runs)
 run.Font.HighlightColor = Color.Yellow;


foreach (Run run in runs)
    run.Font.Color = Color.Black;
    run.Font.Underline = Underline.None;
