I had thousands of game assets and no way to find the one I needed.
I kept buying asset packs and forgetting what was in them. Finding a specific texture meant either remembering the file path or waiting five minutes for Unreal to open. OmniDex is a desktop app that indexes everything locally: search by name, filter by category, see thumbnails and marketplace ratings without opening the engine. Built for the kind of personal organization that large projects depend on.
The Hiraeth project had over a thousand assets and no way to glance at them. No thumbnails without opening the engine, no metadata at a glance. I wanted to type a name and see what I had.
Architecture
Index
Tantivy walks the library, builds full-text index with field boosting
Search
0+ typed IPC commands, every keystroke queries in real time
Results
Thumbnails, ratings, and dependency data extracted from .uasset files
Search returns results in under <0ms across 0+ indexed assets — fast enough to run on every keystroke. The Rust backend exposes 0+ typed IPC commands with a 16-variant error system so every failure mode surfaces a specific message, not a panic.
Tantivy Search with Field Boosting
Tantivy indexes each asset across multiple fields with boosted name matches. Typing "stone wall" surfaces the texture named "stone_wall_diffuse" before a folder that contains it. Fast enough to run on every keystroke.
Name matches boosted 3x, tag matches 2x. Returns results in under 100ms across 1,318+ assets.
