Short answer: "3D search" can mean two related things and each has different logic and benefits.

One meaning is a 3D user interface for search results: items are placed in a spatial scene so users can rotate, zoom, cluster, and compare visually. The other meaning is search inside 3D data (shape/mesh retrieval): algorithms turn geometry into descriptors, index those descriptors, and run nearest‑neighbor queries to find models with similar shape. Both aim to surface visual or structural signals that plain text cannot express.

Why use it (and why not): 3D search helps with discovery, visual similarity, and tasks where geometry or spatial relationships matter (CAD, model libraries, AR/VR product browsing). It leverages spatial memory and parallel comparison. Downsides are higher GPU/CPU cost, occlusion and navigation overhead, longer learning curves, and accessibility issues. Text search remains better for precise, quick lookups, low‑bandwidth devices, and screen-reader friendliness.

Practical guidance (UX + implementation): do not replace text input—offer a text box plus an optional 3D exploratory view. Provide a synced list view, thumbnails, keyboard/navigation controls, shareable URLs, and graceful fallbacks (2D or text) for low‑power devices. On the tech side, render with WebGL/Three.js on the web, use level‑of‑detail and frustum culling for performance, and store geometric descriptors in an ANN index for similarity queries. As and pointed to search links earlier, this note explains the logic, tradeoffs, and when a 3D approach adds real value compared with plain text search.
