vector-search

name	vector-search
description	Semantic vector search for agent-memory. Use when asked to "find similar discussions", "semantic search", "find related topics", "what's conceptually related to X", or when keyword search returns poor results. Provides vector similarity search and hybrid BM25+vector fusion.

Vector Search Skill

Semantic similarity search using vector embeddings in the agent-memory system.

When to Use

Use Case	Best Search Type
Exact keyword match	BM25 (teleport search)
Conceptual similarity	Vector (teleport vector-search)
Best of both worlds	Hybrid (teleport hybrid-search)
Typos/synonyms	Vector or Hybrid
Technical terms	BM25 or Hybrid

When Not to Use

• Current session context (already in memory)
• Time-based queries (use TOC navigation instead)
• Counting or aggregation (not supported)

Quick Start

Command	Purpose	Example
teleport vector-search	Semantic search	teleport vector-search -q "authentication patterns"
teleport hybrid-search	BM25 + Vector	teleport hybrid-search -q "JWT token handling"
teleport vector-stats	Index status	teleport vector-stats

Prerequisites

memory-daemon status  # Check daemon
memory-daemon start   # Start if needed

Validation Checklist

Before presenting results:

• Daemon running: memory-daemon status returns "running"
• Vector index available: teleport vector-stats shows Status: Available
• Query returns results: Check for non-empty matches array
• Scores are reasonable: 0.7+ is strong match, 0.5-0.7 moderate

Vector Search

Basic Usage

# Simple semantic search
memory-daemon teleport vector-search -q "authentication patterns"

# With filtering
memory-daemon teleport vector-search -q "debugging strategies" \
  --top-k 5 \
  --min-score 0.6 \
  --target toc

Options

Option	Default	Description
-q, --query	required	Query text to embed and search
--top-k	10	Number of results to return
--min-score	0.0	Minimum similarity (0.0-1.0)
--target	all	Filter: all, toc, grip
--addr	http://[::1]:50051	gRPC server address

Output Format

Vector Search: "authentication patterns"
Top-K: 10, Min Score: 0.00, Target: all

Found 3 results:

Hybrid Search

Combines BM25 keyword matching with vector semantic similarity using Reciprocal Rank Fusion (RRF).

Basic Usage

# Default hybrid mode (50/50 weights)
memory-daemon teleport hybrid-search -q "JWT authentication"

# Favor vector semantics
memory-daemon teleport hybrid-search -q "similar topics" \
  --bm25-weight 0.3 \
  --vector-weight 0.7

# Favor keyword matching
memory-daemon teleport hybrid-search -q "exact_function_name" \
  --bm25-weight 0.8 \
  --vector-weight 0.2

Search Modes

Mode	Description	Use When
hybrid	RRF fusion of both	Default, general purpose
vector-only	Only vector similarity	Conceptual queries, synonyms
bm25-only	Only keyword matching	Exact terms, debugging

# Force vector-only mode
memory-daemon teleport hybrid-search -q "similar concepts" --mode vector-only

# Force BM25-only mode
memory-daemon teleport hybrid-search -q "exact_function" --mode bm25-only

Options

Option	Default	Description
-q, --query	required	Search query
--top-k	10	Number of results
--mode	hybrid	hybrid, vector-only, bm25-only
--bm25-weight	0.5	BM25 weight in fusion
--vector-weight	0.5	Vector weight in fusion
--target	all	Filter: all, toc, grip
--addr	http://[::1]:50051	gRPC server address

Output Format

Hybrid Search: "JWT authentication"
Mode: hybrid, BM25 Weight: 0.50, Vector Weight: 0.50

Mode used: hybrid (BM25: yes, Vector: yes)

Found 5 results:
----------------------------------------------------------------------
1. [toc_node] toc:segment:abc123 (score: 0.9234)
   JWT token validation and refresh handling...

Search Strategy

Decision Flow

User Query
    |
    v
+-- Contains exact terms/function names? --> BM25 Search
|
+-- Conceptual/semantic query? --> Vector Search
|
+-- Mixed or unsure? --> Hybrid Search (default)

Recommended Workflows

Finding related discussions:

# Start with hybrid for broad coverage
memory-daemon teleport hybrid-search -q "error handling patterns"

# If too noisy, increase min-score or switch to vector
memory-daemon teleport vector-search -q "error handling patterns" --min-score 0.7

Debugging with exact terms:

# Use BM25 for exact matches
memory-daemon teleport search "ConnectionTimeout"

# Or hybrid with BM25 bias
memory-daemon teleport hybrid-search -q "ConnectionTimeout" --bm25-weight 0.8

Exploring concepts:

# Pure semantic search for conceptual exploration
memory-daemon teleport vector-search -q "best practices for testing"

Error Handling

Error	Resolution
Connection refused	memory-daemon start
Vector index unavailable	Wait for index build or check disk space
No results	Lower --min-score, try hybrid mode, broaden query
Slow response	Reduce --top-k, check index size

Advanced

Tuning Weights

The hybrid search uses Reciprocal Rank Fusion (RRF):

• Higher BM25 weight: Better for exact keyword matches
• Higher vector weight: Better for semantic similarity
• Equal weights (0.5/0.5): Balanced for general queries

Combining with TOC Navigation

After finding relevant documents via vector search:

# Get vector search results
memory-daemon teleport vector-search -q "authentication"
# Returns: toc:segment:abc123

# Navigate to get full context
memory-daemon query node --node-id "toc:segment:abc123"

# Expand grip for details
memory-daemon query expand --grip-id "grip:..." --before 3 --after 3
