Fix issue with custom link tags displaying, refs #9351

Fixed issue with our custom link tags displaying, without being converted
to links, in search results. Fixed by converting to HTML then stripping
HTML tags and converting to text. Conversion to text was done so the
text in the results could be easily truncated.
