How soon/often is the google search updated
-
I just now (2011-01-15 00:55 GMT+01) stumbled over a stale result of the google search:
Search for "snipets" (http://developer.qt.nokia.com/search?search=snipets) gives wiki page "Code_Snipets":http://developer.qt.nokia.com/wiki/Code_Snipets, which has been removed recently.
How often resp. when is the google search index updated?

I just checked the Google webmaster stats and yesterday it crawled 8 thousand pages.
We have about 28 thousand pages all in all so it will take a few days to go over them. And I bet Google has some funky algorithm to crawl some pages more frequently than others, so dividing 28 on 8 probably doesn't make sense.

Doesn't look like Google provides that data. (http://code.google.com/apis/customsearch/docs/api.html)
The value of having the date there is marginal isn't it? It wouldn't solve the issue of hitting a page that is no longer there.
