Google: A snapshot of the update
As I said in yesterday's post, Google is currently undergoing major modifications, in which the problem is no more a simple index update, but an in-depth correction of extrapolation routines and boolean logic, in order to fix the count aberrations that I have shown in early February.
The operation must be very difficult, since it seems to have lasted for a month or so. Google has not yet managed to update all its "Data Centers". There seems to be three different groups of Data Centers at this point in time:
- some have not been corrected and still have the previous behaviour (the = 8 billion results, wrong boolean logic)
- some have been partially corrected (the ~ 3 billions, but boolean logic still flawed)
- some seem to have reached the final configuration (the ~ 3 billions, booloean logic fixed).
|Group||Data Center||the||chirac||chirac OR chirac|
See complete list of results.
Various hypothesis can be made. For example, the new algorithms are still under test and for some convenience reasons, the Googles test them only on a subset of machines. Another, deeper reason could be that the update implies not only some mathematical modification in the formulaes, but also a major increase of the main index with respect to the "supplemental" index (see this post). In the latter caser, the limit could very well be a hardware one, and some Data Centers might be awaiting more powerful machines. Nobody can know exactly, but the new kind of Google dance seems quite frantic.
