When you want to search you have to generate this URL https://developers.zomato.com/api/v2.1/search?
lat=LATITUDE
&lon=LONGITUDE
&radius=RADIUS
&establishment_type=ESTABLISHMENT IDS
&category=3%2C10
You can filter by putting multiple categories (in my case, I put "3,10") but whenever I do the same for the establishment types, it's like the API ignored it and showed all the results it could get.
Is there a way to filter the results using multiple establishment IDs?
