AI models process language differently. They understand semantic meaning and context, not just keyword matching. When people query AI tools, they ask complete questions in conversational language: "What's the best WordPress hosting for SaaS applications?" rather than "WordPress hosting SaaS." Your content needs to answer these natural questions directly and comprehensively to appear in AI responses.
The efficiency depends on the query size relative to the data distribution. A small query in a sparse region prunes almost everything. A query that covers the whole space prunes nothing (because every node overlaps), degenerating to a brute-force scan. The quadtree gives you the most benefit when your queries are spatially local, which is exactly the common case for map applications, game physics, and spatial databases.
