Cocosearch quickstart

CocoSearch Quick Start

Get a project indexed and searchable in under 2 minutes. This skill checks prerequisites, indexes the codebase, and verifies everything works.

Step 1: Check Infrastructure

Before indexing, verify the required services are running. The checks depend on which embedding provider is configured.

First, determine the provider: Check cocosearch.yaml for embedding.provider (or the COCOSEARCH_EMBEDDING_PROVIDER env var). If neither is set, the default is ollama. Also check for embedding.baseUrl (or COCOSEARCH_EMBEDDING_BASE_URL).

All providers need PostgreSQL:

1. PostgreSQL (pgvector):

   docker ps --filter "name=postgres" --format "{{.Names}} {{.Status}}"
   

   • If not running: docker compose up -d (from the CocoSearch project root)

Then check the embedding provider:

2a. If provider is ollama (default):

curl -s http://localhost:11434/api/tags | head -c 200

• If not running: docker compose --profile ollama up -d or ollama serve
• If running but no model: ollama pull nomic-embed-text
• If baseUrl is set, check that URL instead of localhost:11434

2b. If provider is openai or openrouter:

• Without baseUrl: Verify COCOSEARCH_EMBEDDING_API_KEY is set:

  echo ${COCOSEARCH_EMBEDDING_API_KEY:+"API key is set"}
  

  If not set: export COCOSEARCH_EMBEDDING_API_KEY=sk-... No Ollama needed.
• With baseUrl: Verify the custom endpoint is reachable:

  curl -s <baseUrl>/v1/models | head -c 200
  

  API key is not required (local OpenAI-compatible servers typically don't need one).

If PostgreSQL + provider checks pass: Proceed to Step 2.

If nothing is running and user has CocoSearch cloned (Ollama provider):

cd /path/to/cocosearch && docker compose --profile ollama up -d

This starts both PostgreSQL and Ollama in one command.

Step 2: Index the Project

Resolve index name (use the resolved name for all operations):

• Try cocosearch.yaml for indexName field -- if found, use it
• If no config file, call list_indexes() and match the current project's directory name against available indexes. The MCP tools auto-derive index names from directory paths (e.g., my-project/ -> my_project), so a match is likely if the repo was indexed without a config file.
• If no match found, the project is genuinely not indexed -- proceed to create one below. Do NOT abandon CocoSearch tools just because cocosearch.yaml is missing.

Check if an index already exists for this project:

list_indexes()

If index exists:

• Run index_stats(index_name="<resolved-name>") to check freshness
• If stale (>7 days): ask "Index is X days old. Reindex to pick up recent changes?"
• If fresh: skip to Step 3

If no index exists, create one:

index_codebase(path="<current-project-root>", index_name="<resolved-name>")

Indexing will:

• Discover all supported files (Python, TypeScript, Go, Rust, Java, C/C++, HCL, Dockerfile, Bash, Markdown, YAML)
• Parse symbols via Tree-sitter (functions, classes, methods)
• Generate embeddings via the configured provider (ollama/nomic-embed-text by default)
• Store everything in PostgreSQL with pgvector

Typical timing: ~30s for small projects (<100 files), 1-2 min for medium (100-500 files), 3-5 min for large (500+ files).

Step 3: Verify the Index

After indexing completes, verify it worked:

index_stats(index_name="<name>")

Check these indicators:

• File count: Should roughly match your source file count (excluding gitignored files)
• Parse health: >80% is good. <80% means some files couldn't be parsed
• Symbol count: Should have functions and classes if the project has them
• Languages: Verify your primary language appears

If parse health is low:

• Run index_stats(index_name="<name>", include_failures=True) to see which files failed
• Common causes: unsupported file types (expected), syntax errors in source files

Linked index health (if cocosearch.yaml has linkedIndexes):

• Check the warnings array from index_stats() for entries starting with "Linked index"
• If any linked indexes are missing or stale, inform the user: "Linked index 'X' is not indexed/stale. Cross-project search won't include it until indexed."

Step 4: Test a Search

Run a quick semantic search to confirm results are meaningful:

search_code(query="main entry point", index_name="<name>")

Good result: Returns the project's main function, CLI entry point, or app initialization — something clearly relevant.

Bad result: Returns unrelated code or no results.

If results are poor:

• Ollama provider: Check that Ollama is running and the embedding model is loaded (curl -s http://localhost:11434/api/tags)
• Remote provider (openai/openrouter): Verify COCOSEARCH_EMBEDDING_API_KEY is set correctly
• Any provider with baseUrl: Verify the custom endpoint is reachable
• Try reindexing: index_codebase(path="<path>", index_name="<configured-name>")
• Try a more specific query related to your project

Done!

Your project is indexed and ready for semantic search. Here's what you can do now:

From the CLI:

cocosearch search "your query"              # Basic semantic search
cocosearch search "query" --hybrid          # Hybrid (semantic + keyword)
cocosearch search "query" -i                # Interactive REPL
cocosearch stats                            # Check index health

From MCP (Claude Code / OpenCode):

search_code(query="your query")
search_code(query="authenticate", symbol_type="function", use_hybrid_search=True)
search_code(query="error handling", language="python", smart_context=True)

Recommended next steps:

• Try the cocosearch-onboarding skill for a guided tour of the codebase
• Use cocosearch-debugging when investigating bugs
• Use cocosearch-refactoring before large code changes
