The location limit feature is available exclusively to our Store Locator Plus Premier/Enterprise customers.
When the URL Control module is active you can enable location ID passing by turning on “Location Limit” under the General / User Interface tab.
When this is enabled you can pass in a limit for the number of locations to be returned when the map initially loads and when a search is performed by adding ?limit=<id> to the end of the page address where your locator map is deployed with the [slplus] shortcode.
Example: Client has 250 results to return by default but when the site via a URL link loaded they only wanted 5 to come back.
Location Limit functionality supersedes the initial default limit.
