ix-search

ast-grep × grep × meaning. Three searches, glued at one spot, with a confidence score.

# pip install ix-search — coming to PyPI; this works today:
pip install git+https://github.com/Intuition-Labs-LLC/ix-search
ix "the part that retries on failure"

That's the whole thing. You already know ast-grep (structure) and grep (text). ix runs both — plus a meaning search — glues the three at the same place, and gives every hit an R: how sure it is, because they agreed.

ix · structure ⊗ text ⊗ meaning, glued by R

  R 1.00  net.py:42    def retry_with_backoff(...)    [ast-grep·grep·meaning]   ← all three agree
  R 0.51  http.py:88   except ConnectionError: ...    [grep·meaning]            ← two agree
  R 0.26  util.py:12   # exponential backoff helper   [meaning]                 ← a stretch, flagged

R = 1 when ast-grep, grep, and meaning land on the same line. Lower when only some do. It's confidence from agreement — not a black-box cosine.

Zero effort

• No API key, no GPU, nothing leaves your machine. Meaning runs on model2vec static embeddings (~30 MB, CPU).
• For an agent: ix "..." --json → {path, line, R, agreed} per hit, so it acts on confidence (take R ≈ 1, escalate R < 1) instead of guessing.

from ix_search import search
for h in search("retry on failure", "."):
    print(h.R, h.path, h.line, h.agreed)

Why it's more than grep

• Three readings glue. Lexical, structural, and semantic search are three views of one location; ix overlays them and scores the agreement. The hit where all three land is the one you want — and the semantic-only stretch is flagged, not hidden.
• Matryoshka = speed. The embeddings are nested (a prefix is a smaller embedding), so ix does a fast coarse pass on a truncated vector, then unfolds to full dim only on the survivors. (--dim tunes it.)

The idea behind it

ix is the runnable instance of The Matryoshka Sheaf — local readings glue into one global result exactly when they agree, with R = exp(−d_tail/scale) as the gluing obstruction.

Needs ast-grep and ripgrep on PATH (the meaning search works without them).
