I want my application to locate entities in and around a given users location coordinates I used the nearsphere function to try and pick out values from my database that are around/within the radius limit. But it keeps turning out an array of empty values fetched. But when i dont provide a radius value and use nearsphere it fetches all the entries in my database, which is not what i want What i have done so far 1. used nearsphere query.nearSphere("_geoloc", 77,0, 11.0, 0.5); which yields 0 results from the resultant evententities Array However if i use nearSphere("_geoloc", 77.0, 11.0); it fetches all the locations in my DB in the resultant array. 2. _geoloc is a column entity in my database, and values are getting stored there too. I am not sure if i have missed out any dependencies, is there an external library or something that needs to be used for this nearsphere function to work properly? Please let me know if any further clarifications or data is required. Thanks in advance!
