Narrative:
During the descent via lucki.1 RNAV arrival into san aircraft encountered wake turbulence from a B737 aircraft approximately ten miles ahead and descending via the same STAR. During the encounter; the aircraft rolled left 30 degrees followed by an abrupt; immediate; and uncommanded descending 40-45 degree roll to the right. Winds aloft were light with about a 15 knot direct headwind noted (approximately FL230).[the first officer] executed a recovery maneuver to level the wings and return aircraft to a normal flight attitude; disconnecting all auto-flight functions. [I] contacted ATC; notified them of the encounter; and requested immediate descent below path of aircraft ahead; which was granted. This allowed us to descend at or slightly below the altitude restrictions on the STAR and place us below the aircraft ahead.noted is the increased utilization of arrivals; which apply very specific lateral and vertical restrictions/crossings. In my experience; these type arrivals have the tendency to place trailing aircraft on a near identical vertical and lateral trajectory of the preceding aircraft and possibly placing the aircraft at a greater risk for this type event.

Title: F2TH Captain reported encountering wake turbulence in trail of B737 while flying the LUCKI ONE STAR to SAN; and that it is plausible that STAR procedures could play a role in increasing these incidents.
