:

private void Find(RichTextBox richTextBox, string term)
{
    var builder = new StringBuilder();

    var inlines = richTextBox.Blocks
        .OfType<Paragraph>()
        .SelectMany(paragraph => paragraph.Inlines);

    foreach( var inline in inlines )
    {
        builder.Append(((Run)inline).Text);
    }

    var regex = new Regex(term);
    var matchedStrings = regex.Matches(builder.ToString());
    foreach( var item in matchedStrings )
    {
        // Whatever you want to do.
    }
}
