Hi, The "rectangular area" refers to a hypothetical map UI. In this scenario, the UI ought to communicate the lat-lon of each corner. The geofilt and bbox query parsers don't handle that; they only take a point and distance.
RE projections: You may or may not need to care depending on exactly what you're doing. Most people by far don't need to care, I've found. Basically: If geo="true" on the spatial field (the default), then you work in decimal degrees latitude,longitude. Point-distance queries (i.e. circles) use spherical geometry. When geo="false", the units are whatever you want them to be (there is no transformation; it's up to you to transform them if needed), and a point-distance (circle) query is on the 2D plane. Other shapes (rectangles, line strings, polygons) use 2D Euclidean geometry no matter if geo=true or false. BTW sorry for my delayed response; I was on vacation. ~ David On Wed, Aug 23, 2017 at 11:21 AM Paweł Kordek <pawel.kor...@outlook.com> wrote: > Hi All > > > I've been skimming through the spatial search docs and came across this > section: > > > > https://lucene.apache.org/solr/guide/6_6/spatial-search.html#SpatialSearch-Filteringbyanarbitraryrectangle > > > "Sometimes the spatial search requirement calls for finding everything in > a rectangular area, such as the area covered by a map the user is looking > at.
