/cognee-recall — Search & Recall from Knowledge Graph

Semantic, graph-traversal, and lexical search across Cognee's knowledge graph. Finds entities, decisions, events, and their relationships — then injects relevant results as agent context for informed decision-making.

Quick Reference

Search Types

Cognee supports multiple search strategies. Use `FEELING_LUCKY` for auto-selection (recommended), or specify one:

| Type | Best for | |------|---------| | `FEELING_LUCKY` | Auto-selects best strategy (default, recommended) | | `GRAPH_COMPLETION` | Relationship-heavy queries ("who owns X", "what depends on Y") | | `GRAPH_COMPLETION_COT` | Complex reasoning with chain-of-thought | | `GRAPH_COMPLETION_CONTEXT_EXTENSION` | Expanding context around a node | | `GRAPH_SUMMARY_COMPLETION` | Summarization of graph neighborhood | | `RAG_COMPLETION` | Retrieval-augmented generation | | `TRIPLET_COMPLETION` | Entity-relationship-entity patterns | | `CHUNKS` | Raw chunk retrieval | | `CHUNKS_LEXICAL` | Keyword/lexical matching | | `SUMMARIES` | Pre-computed summaries | | `NATURAL_LANGUAGE` | Free-form natural language queries | | `TEMPORAL` | Time-based queries | | `CODING_RULES` | Code-specific patterns |

Sub-commands

/cognee-recall search — Run a semantic/graph search

**Procedure:**

1. Ask the user what they're looking for (or use the provided query). 2. Determine the best search type based on the query:

• Queries about relationships → `GRAPH_COMPLETION`
• General "what do we know" → `FEELING_LUCKY`
• Time-based ("last week", "in Q2") → `TEMPORAL` if available
• Code-related → `CODING_RULES`

3. Detect which datasets to search:

• Default: current project dataset
• If user mentions another project: include its dataset
• Use `/cognee status` to list available datasets

4. Execute search:

COGNEE="${COGNEE_BASE_URL:-http://localhost:8000}"

curl -s -X POST "$COGNEE/api/v1/search" \
  -H "Content-Type: application/json" \
  -d "{
    \"query\": \"$QUERY\",
    \"datasets\": $DATASETS_JSON,
    \"search_type\": \"$SEARCH_TYPE\",
    \"top_k\": $TOP_K
  }" | jq .

5. Present results:

COGNEE RECALL — "$QUERY"
==================================================
Found N results across M datasets

[1] DECISION: Use JWT for API auth (2026-06-30)
    Context: Stateless, works with existing infra
    Dataset: my-project | Score: 0.94

[2] ENTITY: Auth Service — depends_on → PlatformHub
    Description: Authentication and authorization service
    Dataset: my-project | Score: 0.87

[3] TASK: Set up JWT middleware (open, priority 1)
    Assigned to: Alice Chen
    Dataset: my-project | Score: 0.82

/cognee-recall context — Inject results as agent context

Same as search, but formats results for direct injection into the agent's context window. Use this before making architectural decisions or when context from past sessions is needed.

**Procedure:**

1. Run search as above. 2. Format results as a compact context block:

[COGNEE CONTEXT INJECTION — {timestamp}]
Query: "{original_query}"
Dataset(s): {dataset_names}

Relevant knowledge:
• DECISION ({date}): {text} — {context} [relevance: {score}]
• ENTITY: {name} ({type}) — {description} [relevance: {score}]
• TASK: {text} ({status}) — assigned to {assignee} [relevance: {score}]
• EVENT: {title} ({date}, {type}) — {summary} [relevance: {score}]

Use this context to inform your response. Cite specific decisions and entities where relevant.

3. The agent then uses this context transparently in its reasoning.

/cognee-recall graph — Explore entity neighborhood

Explore the graph around a specific entity to understand its relationships.

COGNEE="${COGNEE_BASE_URL:-http://localhost:8000}"

# First, get the dataset ID
DATASET_ID=$(curl -s "$COGNEE/api/v1/datasets" | jq -r '.[] | select(.name=="my-project") | .id')

# Get the full graph
curl -s "$COGNEE/api/v1/datasets/$DATASET_ID/graph" | jq .

Present as a relationship map:

ENTITY GRAPH — "Auth Service" (my-project)
