Gabriel39 opened a new pull request, #4148: URL: https://github.com/apache/doris-website/pull/4148
Document how to query a Lance multi-vector column with `vector_search()`, including data preparation, expected results, scoring, index usage, and parameter limits in the English and Chinese 4.x Lance Catalog guides. Depends on https://github.com/apache/doris/pull/68028; merge the documentation with or after that implementation. Related feature request: https://github.com/apache/doris/issues/66494. The guide explains supported Arrow types and nullability, row-level L2/cosine/dot scoring, matrix dimensions, the 128-subvector limit, both 100,000-candidate budgets, mandatory multi-vector refinement, and cosine index usage. It also corrects the metric/refinement defaults and reader versions to match the implementation. ## Versions - [ ] dev - [x] 4.x - [ ] 3.x - [ ] 2.1 or older (not covered by version/language sync gate) The Dev Lance Catalog pages were deliberately removed in https://github.com/apache/doris-website/pull/4086. This change updates the existing 4.x pages without restoring those pages or advertising support in older releases. This explains the existing missing-current-counterpart warning from the locale/version check. ## Languages - [x] Chinese - [x] English ## Validation - Reviewed the complete diff against the FE parameter validation and Lance C multi-vector scoring implementation. - Compiled both changed MDX files with GFM/front matter support and normalized Docusaurus explicit heading IDs. - Changed-file link and feature checks: no errors. The external Lance object-store documentation was checked separately. - Verified that both locales contain identical executable examples. Executed the data builder using pylance 11.0.0 with temporary local storage, then checked the documented basic, offset, and prefilter results through the patched Lance C scanner, including empty/null outer rows. - `git diff --check` passed. - No full-site build or new live Doris SQL run. SEO checks reported only existing metadata warnings; no metadata is changed. ## Docs Checklist - [x] Checked by AI - [x] Test Cases Built - [x] Updated required version and language counterparts, or explained why not - [x] If only one language changed, confirmed whether source/translation counterparts need sync -- This is an automated message from the Apache Git Service.
