I have indexed geodata from multiple people who visited different places. Now I only want to show places where 2 or more people were close to each other (max 100 meter apart from each other).
I need to do this without hardcoding an origin. Is this even possible?
In the end I would like to combine this with the timestamp (available in the same documents) to filter on time as well (max 10 minutes apart from each other for example).
I am struggling to get this done in Kibana, but thought I should start with DSL itself before moving towards maps.
