Data Refresh

Within a data refresh the algorithm used by the search engine does not change. It is instead the data that is fed into the algorithm is updated.

In Google, due to the technological system in play through multiple data centres, data refreshes happen often. If you do a search from home and them from work you may find that you get differing results. This is partially due to the fact that the data centre you are querying in each location is different. Over time the data held by the data centre may change and evolve to be different in some ways from information held on other data centres. A data refresh places the same information on all data centres in a rolling manner to ensure that the results delivered across the Google network are as consistent and accurate as possible.
