from bhoonidhi.SmartSearch import bhoonidhiSmartSearch
from bhoonidhi.SmartSearch import bhoonidhiDownload

user_query = "I want Landsat8 and Sentinel 2A data from the region of Guntur over the radius of 20 km and cloud threshold of 35%"
bhoonidhiProducts = bhoonidhiSmartSearch(user_query)
# Want to download the 12th product from the response, pass the 12th response product object
