sgrep

name	sgrep
description	Semantic and hybrid code and conversation search for intent-based queries. Use when exploring unfamiliar codebases, finding code by concept instead of exact text, or recalling past agent conversations about similar problems.
license	Apache-2.0
compatibility	Requires the sgrep binary; semantic and conversation indexing use a local llama.cpp-compatible embedding server.

sgrep - Smart Code & Conversation Search

Use sgrep for semantic and hybrid search across code and agent conversations. It understands intent, not just exact strings.

When to Use

Code Search

• Finding code by concept: "error handling", "authentication logic", "rate limiting"
• Searching for specific terms with semantic context: use --hybrid
• Best code-search accuracy after indexing: use --hybrid --colbert
• Exploring unfamiliar codebases
• When ripgrep patterns keep missing relevant code

Conversation Search

• Finding past discussions with Claude Code, Codex CLI, Cursor, OpenCode, or Pi
• Recalling how you solved a similar problem before
• Building context from previous sessions for new tasks
• Searching across all your coding agent interactions

Commands

# First time only
sgrep setup
sgrep setup --with-rerank  # optional, only for --rerank

# Index current directory; builds compact TQ-MSE chunk/file vectors by default
sgrep index .

# Optional ColBERT segment codec override
sgrep index . --colbert-codec tqmse
sgrep index . --colbert-codec int8
sgrep index . --colbert-codec pq6

# Legacy compatibility: also persist full SQL vectors
sgrep index . --sql-vectors

# Watch mode keeps SQL vectors for incremental updates; rerun index to compact
sgrep watch .

# Balanced semantic + lexical code search (default)
sgrep "database connection pooling"
sgrep "how are errors handled"

# Fast semantic-only search
sgrep --profile fast "error handling"

# Best code-search accuracy
sgrep --profile quality "JWT validation"
sgrep --profile quality "authentication middleware"

# With code context
sgrep -c "authentication middleware"

# JSON output
sgrep --json "rate limiting"

Conversation Search

# Index conversations; refreshes compact TQ-MSE turn vectors
sgrep conv index
sgrep conv index --source codex
sgrep conv index --source claude
sgrep conv index --source opencode
sgrep conv index --source pi
sgrep conv index --watch
sgrep conv index --force

# Search conversations
sgrep conv "authentication flow"
sgrep conv "JWT refresh_token" --hybrid
sgrep conv "database migration" --agent claude --since 7d
sgrep conv "bug fix" --project payment-service --after 2026-01-01 --before 2026-06-01
sgrep conv "exact phrase" --exact
sgrep conv "auth" --json -n 1

# View, export, context, and copy helpers
sgrep conv view <session_id>
sgrep conv view <session_id> --turn 3 --no-color
sgrep conv export <session_id> --format markdown -o conversation.md
sgrep conv export <session_id> --format json -o conversation.json
sgrep conv context <session_id>
sgrep conv context <session_id> --turns 10 --copy
sgrep conv copy <session_id> --turn 2 --code-only
sgrep conv status

Semantic vs Hybrid

Mode	Best For	Example
--profile fast	Lowest-latency semantic exploration	"how does auth work"
--profile balanced (default)	Semantic + exact-term recall	"JWT token validation"
--profile quality	Highest code-search accuracy	"authentication middleware"

Use the default balanced profile for most agent searches and --profile quality when ranking quality matters more than minimum latency.

Search Hierarchy

1. sgrep → Balanced semantic + lexical discovery
2. sgrep --profile fast → Lowest-latency semantic discovery
3. sgrep --profile quality → Rerank candidates with precomputed late interaction
4. ast-grep → Match structural patterns in those files
5. ripgrep → Exact text for specific symbols
