Dear Analytics Mailing List, Recently while querying pageviews of various pages, I discovered that the page whose title is a single hyphen character (i.e. with the title "-", with URL <https://en.wikipedia.org/wiki/->, which redirects to <https://en.wikipedia.org/wiki/Hyphen-minus>) receives an unusually high number of pageviews under the Pageview API. Taking October 2015 as an example, the page received 5.4 million pageviews during that month according to the API: < https://wikimedia.org/api/rest_v1/metrics/pageviews/per-article/en.wikipedia/desktop/user/-/daily/20151001/20151031 >.
However, according the stats.grok.se (which was still operational in the same month), the page received only 1209 pageviews: <http://stats.grok.se/en/201510/->. Looking at the tabulation of pageviews on Wikipedia Views, the increase in pageviews for this page coincides with the change to the Pageview API in July 2015: < http://wikipediaviews.org/displayviewsformultiplemonths.php?page=-&allmonths=allmonths&drilldown=all >. As I understand, page titles must be URL-encoded before the query, but the URL-encoding of "-" is itself. I looked at the API documentation but did not see this behavior listed, so I am wondering where these numbers are coming from. Best regards, Issa
