Overpass API: efficient query for location names around given coordinates

Hi there,

currently I'm searching for 4 types of features along a certain path (e.g. a point every 20 meters on a given track). I want to query for location names (e.g. mountains, rivers, huts, cities) around these coordinates.

Currently my queries look like this:

[out:json][timeout:30];
(
 node(around:50,46.512,7.827) ["natural"];
 node(around:50,46.512,7.827) ["highway"];
 node(around:1500,46.512,7.827) ["place"];
 node(around:50,46.512,7.827) ["tourism"];

 node(around:50,46.512,7.827) ["natural"];
 node(around:50,46.512,7.827) ["highway"];
 node(around:1500,46.512,7.827) ["place"];
 node(around:50,46.512,7.827) ["tourism"];
); 
out body;

The block inside (4 types) is repeated for each coordinate.

Because I'm querying several hundred coordinates for features at once: Is there a more efficient way doing this? Or can I combine all the queries around 50 meters for "natural", "highway" and "tourism"?

Thank you! Jens
