When you do a search on a city, how can you make sure you search on the city or on the zipcode. Now he does an entire search but it has results I don't want to have.
For example you search 'new york' you get results as "new york-street, ... " but not ONLY new york.
You can't. You need to modify the source code to only search in the city name. We actually have a plugin event onAfterBuildQuery - it would give you the query as parameter and you can modify it - remove the search in description, street etc. But you would need to write php and sql for this. The benefit obviously is that when you update hotspots, your changes in the plugin will stay untouched.
