As I mentioned on my project proposal, I promised to contribute not only for search API location module, but also any other modules related to my proposal i.e to make drupal users have experience a great geo spatial search. If you see my previous post, for the time being I had to remove geocoder plugin as search api location plugins were not visible.
If you remember in the previous post, I submitted tests for location data type, and location input plugin i.e raw input plugin. Although there are three location input plugins available i.e raw, geocoder and map. But as I discussed with my mentor and came across a solution that to release a working search_api_location module with only raw input plugin at the end of this month. Because geocoder module is not stable yet.
