indexion search — Codebase Search & Exploration

Find what you need in a codebase. This skill covers every search intent — pattern matching, structural queries, semantic similarity, file-level exploration, and purpose-based function lookup — and tells you which tool to reach for based on what you're actually trying to do.

Start Here: What Are You Looking For?

Don't pick a command first. Start with your intent.

"Where is X defined / used?"

You know the name. You need to find it.

Exact name match — Ident:X matches the exact token text. Finds definitions and all call sites:

# Find a type definition and all references
indexion grep "TypeIdent:DigestManifest" src/

# Find only the function definition (fn keyword + identifier)
indexion grep "fn Ident:parse_config" cmd/

# Find both definition and call sites (Ident without fn)
indexion grep "Ident:parse_config" cmd/

# List all pub struct definitions
indexion grep "pub struct *" src/

Substring match — --semantic=name:X matches as a substring. Use when you don't remember the exact name:

# Find all functions containing "build_graph" (matches build_graph_from_source too)
indexion grep --semantic=name:build_graph src/ cmd/

# Find all functions containing "sort"
indexion grep --semantic=name:sort src/

Ident:build_graph only matches a token with exactly that text. To find build_graph_from_source, use --semantic=name:build_graph instead.

Token-level search — indexion grep is not text grep. It searches over the token structure defined by KGF specs. pub fn * matches the keyword pub, the keyword fn, then any identifier — it won't match pub fn inside a string literal or comment.

Pattern syntax:

Pattern	Meaning
pub, fn, for	Language keyword (auto-resolved via KGF aliases)
KW_fn	Token kind exactly
Ident:foo	Kind + text (exact match)
*	Any single token
...	Zero or more tokens (non-greedy)
!pub	Negation — any token except this
(, ), {, ->	Punctuation (aliases)
