A hybrid ranker weighs meaning, keywords and graph connections together, and every answer comes back with its sources." url: https://surrealdb.com/agent-memory/recall --- RECALL # Recall you can trust Every turn, agent memory feeds the context window the slice that matters - and recall is engineered for correctness. A hybrid, multi-signal ranker weighs meaning, exact keywords, and graph connections together, and every answer comes back with the exact sources behind it.

Only real retrieval runs the full fusion, with a broader sweep held in reserve for when the answer is thin - so recall is fast when it can be and thorough when it must be.

Learn more ### [Lexical (BM25)](https://surrealdb.com/agent-memory/deep-dive) Exact keyword matching, so specific terms are never lost to paraphrase. Learn more ### [Graph traversal](https://surrealdb.com/agent-memory/knowledge-graph) Connected entities pulled in through typed relationships. Learn more ### [Personalised PageRank](https://surrealdb.com/agent-memory/deep-dive) Importance weighted by how memories connect, not just how they read. Learn more ### [Keyword bridges](https://surrealdb.com/agent-memory/deep-dive) Shared terms link memories that vector similarity alone would miss. Learn more ### [Sources on every answer](https://surrealdb.com/agent-memory/provenance) Recall returns the exact records behind each result, ready to cite. Learn more 02 |ONE SUBSTRATE ## Similarity alone gets the wrong thing A pure vector search returns what reads similarly - which is not always what's true, current, or relevant. Agent Memory fuses multiple signals and reconciles what changed, so recall surfaces the right thing, with its sources. ### Tiered, so it stays cheap Direct lookups answer from the graph; only genuine retrieval runs the full fusion. Cost tracks difficulty, not volume. ### Reconciled, not stale Superseded facts step aside for the current one, so recall reflects what's true now, not what was said first. ### Provable, every time Each answer carries the exact records behind it, so nothing recall returns is a black box. ## Keep exploring ### [Provenance](https://surrealdb.com/agent-memory/provenance) How every answer traces back to its source.
