There is no option to limit by week.

In Summon Analytics (Current), the "Popular Searches weekly report " actually returns "Popular Searches in the last 2 months".
The report does not have the option of applying weekly time frames.
The title given to the search suggests that someone thought weekly reports would be desirable, but they did not provide the option of week.
subject area: popular searches

Data is not currently available weekly. Ex Libris will need to change its data collection method in order to resolve this.
In the meantime Ex Libris will change the label from "weekly" to "monthly" so that the report is not misnamed.
