# Memory Search (SOTA) State-of-the-art semantic search across Ruflo memory with multiple retrieval strategies. ## Strategy Selection Choose based on query type: - **Default** (dense): fast single-hop semantic match - **--hybrid**: sparse + dense with RRF fusion (20-49% better for keyword+semantic queries) - **--graph-rag**: multi-hop knowledge retrieval (30-60% better for reasoning queries) ## Steps 1. **Parse query and flags** — extract search text and strategy flags from arguments 2. **Select retrieval strategy**: **Dense search (default)**: ```bash npx @claude-flow/cli@latest memory search --query "QUERY" --namespace NAMESPACE --limit 10 ``` Or via MCP: `mcp__plugin_ruflo-core_ruflo__memory_search({ query: "QUERY", namespace: "NAMESPACE", limit: 10 })` **Hybrid search** (when --hybrid or query has specific keywords): ```bash npx ruvector search "QUERY" --hybrid --limit 10 ``` **Graph RAG** (when --graph-rag or multi-hop reasoning needed): ```bash npx ruvector search "QUERY" --graph-rag --limit 10 ``` **Smart retrieval** (when --smart or complex recall needed): ```bash npx @claude-flow/cli@latest memory search --query "QUERY" --smart --limit 10 ``` Or via MCP: `mcp__plugin_ruflo-core_ruflo__memory_search({ query: "QUERY", smart: true, limit: 10 })` Applies 5-phase pipeline: query expansion, RRF fusion, recency boost, MMR diversity, session round-robin. Best for: multi-session recall, temporal queries, diverse result sets. **Unified cross-namespace**: `mcp__plugin_ruflo-core_ruflo__memory_search_unified({ query: "QUERY", limit: 10 })` 3. **Apply MMR reranking** — for diverse results, filter near-duplicates (cosine > 0.92) while maximizing relevance 4. **Apply recency weighting** — boost recent entries with exponential decay (0.95/day) 5. **Synthesize context** (for complex queries): `mcp__plugin_ruflo-core_ruflo__agentdb_context-synthesize({ query: "QUERY", sources: ["patterns", "tasks", "solutions"] })` 6. **Present results** — ranked by composite score (relevance * diversity * recency), with source namespace attribution ## Namespace Guide | Namespace | Best For | |-----------|----------| | `patterns` | "How did we handle X?" | | `tasks` | "What was the context for Y?" | | `solutions` | "How did we fix Z?" | | `feedback` | "What did the user prefer?" | | `security` | "Known vulnerabilities in..." | | (omit) | Search all namespaces |
