Four-State Search

Every query returns four distinct classifications, not just matches.

+

Affirmed

Explicitly confirmed. Stable APIs, featured shaders, high-quality resources.

−

Denied

Explicitly negative. Deprecated APIs, broken shaders, known incompatibilities.

~

Mentioned

Present but neutral. Experimental APIs, medium-quality resources, referenced terms.

0

Absent

Not found anywhere. Confirms what doesn't exist — equally valuable information.

Under the Hood

APOLLO is built on Trinity — a search engine designed for structured knowledge.

Four-State Search

Every query returns affirmed, denied, mentioned, and absent results. Know what exists AND what doesn't.

Shadow Indexing

Source code and documentation are tokenized against the existing dictionary. Zero dictionary cost, full searchability.

Sub-Second Queries

Compressed position indexes and SQL-backed search deliver instant results across 55 databases and 141K+ documents.

Blazing Fast

Sub-second queries across all databases. Optimized batch-mode indexing with 23MB RAM footprint.

Typed Value Channels

Numbers, dates, and IDs bypass the dictionary and route through dedicated typed value tables for precise queries.

Cross-Category

Shared vocabulary across categories enables correlations that were never searchable together before.
