Powerpoint VSTO TextRange.Find() only finds one result in Shape

Currently using the PowerPoint VSTO API to search for words within a PowerPoint presentation.

Bumped into an issue when searching a TextRange within a shape for a string with the expectation of more than one result to return.

The text I am doing the find on is (I have bolded the words to bring attention to them, they are not like this in the original):

This is some text

  • Colour vs color
  • Some filler text
  • Some other filler text
  • Formalize vs formalise
var shape = presentation.Slides[1].Shapes[2];

var findResults = shape.TextFrame.TextRange.Find("vs", 0, MsoTriState.msoFalse, MsoTriState.msoFalse); 

var count = findResults.Count; //Expected 2, but only found 1

Any thoughts? I was expecting two results but at the moment I am only getting one, the first range "Colour vs color".

Edit: Solution Putting this here in case someone else comes across this (or I forget).

Did some more digging and I discovered the int after argument in the Find() VSTO API. Essentially the after argument moves the range to search area on a number of characters you pass it. So passing in the end range of the first result and calling the .Find() again returns the next instance I was looking for.

For example:

var shape = presentation.Slides[1].Shapes[2];

var findResults1 = shape.TextFrame.TextRange.Find("vs", 0, MsoTriState.msoFalse, MsoTriState.msoFalse); 
//Returns the first vs instance "Colour vs color"

var findResults2 = shape.TextFrame.TextRange.Find("vs", (findResults.Start + findResults.Length), MsoTriState.msoFalse, MsoTriState.msoFalse); 
//Returns the second vs instance "Formalize vs formalise"
