This plugin gathers data about searches that users make on your site.
Notes on the analysis of the data:
The search results used for Dynamic album processing are ignored.
Analysis presumes that the Theme does a "uniform" set of object retrievals. That is, the search.php script will always request albums, images, pages, and/or news consistently. Data collection happens for each of these objects so to "normalize" the data the analysis will divide the data by the number of objects searched.
So, if for instance, you sometimes enable Zenpage results, sometimes there will be results for images, albums, pages, and news; and other times there will just be results for images and albums. In this case the reports will under value the searches done when Zenpage results were not enabled.
