Google won't let you specify just this website, but if you want to confine your search to here: -
That will have almost the same effect as searching just this site.
Google "crawls" this website periodically, updating its index. Whether or not the results are up-to-date depends on how recently Google was last here. To know when Google was last here, search for "vire 7" and "updates", and take a moment to view Google's cache of the page and note the date of the most recent update. Then, to be sure not to miss anything, check the list of updates on the website to see the latest additions.
When Google displays the results of its search, it may also present some advertisements. Allowing them to do this is the price that I pay for being allowed to use Google as my dedicated search engine.
