Using the Aspose.PDF library, I am able to highlight full words using regex and I can highlight substrings. But what is the code I should use if the substring continues onto a different line?

Using the above as an example. On the first page in the second column is the substring ‘how to save your logo’ that extends to two lines. I want to programmatically search and highlight that substring. How would I go about this?
