Perform your spatial query and create a new attribute field to hold a Boolean value. Then use Layer->Query and set the standard filter to your Boolean value (this will hide all the other points). Set the display style of your points to be 100% transparent and then perform the spatial query.

This software also supports other spatial statistical tools for linear regression and spatial regression, and furthemore spatially varying coefficients. This is a stand-alone software package mainly for Moran eigenvector spatial filtering (MESF) in a geographic information systems (GIS) environment. This tool also supports other spatial statistical tools for linear regression and spatial regression, and furthemore spatially varying coefficients.

That's the core idea of a database. It's a join, and when you have spatial functions, you can do that join based on spatial conditions. It becomes a spatial join. Once you get that join, you can do other things. spatial filtering. Spatial filtering beautifully demonstrates the technique of Fourier transform optical processing, which has many current applications, including the enhancement of photographic images and television pictures.
