Could you build this?
Partial While wrapping SQLite FTS5 or Tantivy into a CLI tool is manageable, writing a high-performance custom ranked full-text indexing engine from scratch requires deep information retrieval knowledge.
What it would actually take: Typically built in Rust or Go using high-performance search libraries (e.g., Tantivy) or implementing BM25/TF-IDF inverted indexes over memory-mapped files. The hard part is building zero-dependency, crash-safe, multi-gigabyte disk serialization, tokenizers for varied data formats, and ultra-fast sub-millisecond ranked vector/lexical retrieval in a single static binary.
