It is now possible to use the Google Search on the phpBB SEO domains.
You can search among topics (only URLs to be cached here) directly from the phpBB Search Pages :
Search - Rechercher
Google search results are a lot better than phpBB's, with almost no delay since this site is cached quite fast.
[EDIT] So we go for new page for results for now, which works as follow :
English Speaking Search :
French Speacking Search :
The French-speacking Poll is here.
