Noticed over the last couple of weeks that the forum search function only shows limited and very recent results. However, if I use a search engine (eg Google) with the exact same keywords and the prefix 'site:www.camaros.org' it will show the thread I'm looking for.......
Example: was searching for an old thread about Paragon Reproductions today; searching from within the forum for the keyword 'Paragon' only found today's posts. Google threw up the thread from some years ago that I was looking for.
