How to extract more data from google maps

Google company by default allows only 60 contacts to be extracted using their api per query. This means if you type mumbai as the location and doctor as category, it will extract only 60 contacts. But how can we extract more? Well to extract more contacts you can extract data using pincodes as location. So instead of typing mumbai as location, we will type or paste list of all the pincodes in mumbai. But while typing the pincodes you need to type comma india. 
Example:
400001,india
400002,india
400003,india 
(View the image below.)

you can download the list of pincodes from google, or you can also click on this link here to download the list of pincodes in india. 

Also remember, that the radius should be reduced to 1000 or 1500. (view the image below)
