Stores Locator Not Working After Bulk Import

[prestatent]

Prestashop 1.5.4.1

Hi

I've loaded in 960 new locations in prestashop table ps_store. When I then search by location it does not show these new stores.

 

When I edit a product and save it without changing any details, the store now shows in the store locator.

 

I'm assuming that an index or some script has to be re-run to add all these new locations into the index. If so, where can I run this script?

 

Thanks for any help.
