Retrieval Engine Capabilities

Grounding answers in your own indexed content.

TF-IDF & BM25 Retrieval

Combine TF-IDF scoring with BM25 keyword matching, stemming, and synonym expansion, so technical terminology and exact phrases are retrieved accurately.

Strict Fact Boundaries

Configure hard context guardrails that force the model to declare "Information unavailable" rather than guessing or fabricating answers.

Automated Indexing Pipelines

Ingest Markdown, HTML, JSON, or plain text documentation directly into local SQLite tables, with zero external database costs.

Answer-First Citation Schema

Structure returned answers with direct reference links pointing to the exact documentation source page for complete auditability.
