Aloglia：用于地理搜索的索引圈位置区域

Question

Is it possible to index a circle zone and make it work with Algolia geo-search.

The only solution I can come with is to index multiples points of the circle like that :

"_geoloc": [
  { "lat": 47.279430, "lng": 5.106450 },
  { "lat": 47.293228, "lng": 5.004570 },
  { "lat": 47.316669, "lng": 5.016670 }
]

But I think it wont be very accurate unless I have a lot of points. Any thoughts ?

Answer 1

It's not possible to index a circle or a polygon as a location.

I'm not an expert of geolocalization in general but I have never came across this. I think a place is always represented as a single couple of coordinates (lat, lng).

I think if you want to index large places, you'll have to increase the radius at search.

Your idea of indexing multiple points makes perfect sense tho.
