+## Scheduled searches (weekly review)
+
+**Schedule** saves the current filters as a search that the server runs on its own:
+every week (day and time), every day, or every N hours, in the server time zone (`TZ`).
+Each run keeps a snapshot of the first 30, 50 or 100 results.
+
+The **Watch** tab lists the scheduled searches with their last run, and a review page
+per search shows, for any run of its history:
+
+- **New**: repositories never returned by a previous run of this search;
+- **Rising**: repositories that gained the most stars since the previous run;
+- **All**: the whole snapshot, with the star gain of each repository.
+
+A search runs once as soon as it is created: that first run is the baseline the next
+ones are compared with. A run missed while the server was stopped is made at startup.
+For a weekly "gems" review, a good start is: a topic or a language, *created < 1 month*
+(or *< 1 week*), sorted by *most stars*.
