Description

Besides query based on category or property, a powerful query method is available through distance query.

https://www.semantic-mediawiki.org/wiki/Semantic_Maps_examples/Distance_query

I wonder if there's a way to query points by setting a polygon and search for points inside a polygon. This would be no different than distance query (setting a center and a distance from the center) but in reverse.

The distance query is good if you're looking at a square area, but it wouldn't work if the area that you want to query a point is not a square.

Comparison of what I can do with distance query and the polygon that I want the system to search for points inside:

Research direction

Start by reading the linked Semantic Maps distance-query examples and compare them with the polygon example in the issue. Identify the existing distance-query entry point and determine how polygon geometry would be supplied; done means a query can return points contained by a specified polygon.
