@copilot the solution is not satisfactory. Access the nitrite-java related changes in nitrite/nitrite-java#1086 and see how all changes has been done in spatial module only. Make similar changes here. All changes should go to nitrite-spatial module only. |

Pull request overview
This PR fixes false positives in spatial filter queries by implementing the FlattenableFilter pattern from nitrite-java PR #1086. The issue occurred when geometries had overlapping bounding boxes but didn't actually intersect - the R-Tree index would return false positives based on bounding box checks alone.
Key Changes:
- Implemented two-stage filtering: fast R-Tree index scans on bounding boxes, followed by accurate JTS geometry validation
- Introduced
FlattenableFilterinterface to decompose spatial filters into index-scan and validation components - Added comprehensive test coverage for false positive scenarios with intersects and within filters

The geometry extraction logic (lines 258-292 in _NearValidationFilter.apply) is duplicated from _GeometryValidationFilter.apply (lines 54-89). Consider extracting this into a private helper method like:
Geometry? _extractGeometryFromDocument(Document doc, String field) {
var fieldValue = doc.get(field);
if (fieldValue == null) return null;
if (fieldValue is Geometry) {
return fieldValue;
} else if (fieldValue is String) {
try {
var reader = WKTReader();
return reader.read(fieldValue);
} catch (e) {
return null;
}
} else if (fieldValue is Document) {
try {
var geometryString = fieldValue['geometry'] as String?;
if (geometryString != null) {
return GeometrySerializer.deserialize(geometryString);
}
} catch (e) {
return null;
}
}
return null;
}This would improve maintainability and ensure consistency across both validation filters.
