When to Use This Skill

• User asks to search files, documents, or notes
• User wants to find information in local folders
• User needs to index a directory for searching
• User mentions PDFs, markdown, Word docs, code to search
• User asks about knowledge base or RAG setup
• User wants semantic/vector search over their files
• User needs to set up MCP for document access
• User wants a web UI to browse/search documents
• User asks to get AI answers from their documents
• User wants to tag, categorize, or filter documents
• User asks about backlinks, wiki links, or related notes

Search Modes

Command	Speed	Best For
gno search	instant	Exact keyword matching
gno vsearch	~0.5s	Finding similar concepts
gno query --fast	~0.7s	Quick lookups
gno query	~2-3s	Balanced (default)
gno query --thorough	~5-8s	Best recall, complex queries
gno ask --answer	~3-5s	AI-generated answer with citations

Retry strategy: Use default first. If no results: rephrase query, then try --thorough.

Common Flags

-n <num>              Max results (default: 5)
-c, --collection      Filter to collection
--tags-any <t1,t2>    Has ANY of these tags
--tags-all <t1,t2>    Has ALL of these tags
--json                JSON output
--files               URI list output
--line-numbers        Include line numbers

Global Flags

--index <name>    Alternate index (default: "default")
--config <path>   Override config file
--verbose         Verbose logging
--json            JSON output
--yes             Non-interactive mode
--offline         Use cached models only
--no-color        Disable colors
--no-pager        Disable paging

Non-default index search results may include ?index=<name> on gno:// URIs. Keep that query string when passing the URI to gno get.

Important: Embedding After Changes

If you edit/create files that should be searchable via vector search:

gno index              # Full re-index (sync + embed)
# or
gno embed              # Embed only (if already synced)

MCP gno.sync and gno.capture do NOT auto-embed. Use CLI for embedding.
