// 1. Isolate the content block we want to search in.
// Assume the block we care about is between BEGIN and END.

var endIndex = document.IndexOf("]END");
var contentLength = endIndex - startIndex;

// 2. Perform a find operation on just that substring.
var t = uc.NewTransformer().SetText(contentBlock);
t.Pattern("find");
t.Find();
var matches = t.Matches;

Console.WriteLine($"Local match StartPosition: {matches[0].StartPosition}"); // Relative to 'contentBlock'

// 3. Apply the offset to remap to the global 'document' coordinate space.
matches.ApplyOffset(startIndex);
