Search Functionality

Hi. Thanks for the great plugin. I have a support request that I need to perform a text search functionality in the map. A simple Textfield and a Submit button. Upon submit the map must filter based on the input given. I have seen the global search in the map, but it searches all locations, beyond the actual markers present in the map. So I need to search and filter the existing markers from an input given. I hope its clear. Awaiting for the reply.

Thanks…
