tara created a nice little script for date-based searching using the google api:
“”What if you gave Google a query and a certain number of days back you wanted to go, and Google just pulled the number of results for each day and then wrote them to a file, so you’d have an idea of how often a query word set appeared in indexed results over time.””
if you did a little deviation detection and multiple correlation analysis with thresholding, filtering and notification, you could have a nice little “business intelligence” application.
for example, it’d be pretty handy to easily look at correlated deviations in frequency, “notify me when “wlan” and “nokia partnerships” occur more often than normal in a single month.”
