In order for a post to be searchable via GEO my WP the post needs to have its location saved in GEO my WP database table. To do so you will need to either save the post ( event in your case ) location using GEO my WP location section or use a custom function provided by GEO my WP to link the location being saved by the plugin that you are using to GEO my WP.
