Xuanwo 5bfde47a8e fix: support nested field paths in native index creation (#3408)
Native index creation was resolving requested columns through top-level
Arrow schema lookup before handing the request to Lance, which rejected
nested paths and could collapse a nested field to its leaf name. This PR
resolves index targets with Lance field-path semantics, passes the
canonical path through to Lance, and reports indexed columns from field
ids as canonical full paths.

This also removes the Python native FTS guard that rejected dotted paths
so scalar, vector, and FTS index creation share the same nested-field
contract. Related to #3402.

LanceDB Python SDK

A Python library for LanceDB.

Installation

pip install lancedb

Preview Releases

Stable releases are created about every 2 weeks. For the latest features and bug fixes, you can install the preview release. These releases receive the same level of testing as stable releases, but are not guaranteed to be available for more than 6 months after they are released. Once your application is stable, we recommend switching to stable releases.

pip install --pre --extra-index-url https://pypi.fury.io/lancedb/ lancedb

Usage

Basic Example

import lancedb
db = lancedb.connect('<PATH_TO_LANCEDB_DATASET>')
table = db.open_table('my_table')
results = table.search([0.1, 0.3]).limit(20).to_list()
print(results)
