Gabriel39 opened a new pull request, #4554: URL: https://github.com/apache/doris-website/pull/4554
## What is changed Document the `approx_mode` property added by https://github.com/apache/doris/pull/69852 in the English and Chinese 4.x Lance Catalog pages. This is the companion website documentation for that feature; merge it together with or after the implementation. The parameter reference and new guidance cover: - Accepted values and default omission; index-specific differences between `fast`, `normal`, and `accurate`. - A workload selection table and tuning order using exact ground truth, recall, latency, and original-vector refinement. - ACORN prerequisites, a SQL example, per-HNSW-subindex filtering thresholds, fallback behavior, and the limits of EXPLAIN. - The coupled ACORN and RabitQ scoring effects on compatible HNSW/RabitQ indexes; HNSW_FLAT measurements do not establish the combined index's recall. - Lookup-table precision versus stored encoding bits, approximate versus exact results, and FE/BE upgrade compatibility. The detailed native validation measurements are recorded in the implementation PR. The temporary guide in the Doris source repository is being removed in favor of this website documentation. ## Validation and scope - Both changed pages compiled successfully with the Docusaurus MDX processor. - Ran the documentation governance checks and compared them with the same checks on the unchanged base content. No new warnings or errors; the only new informational entries report the public implementation-PR links. - Reviewed the complete diff and Chinese/English parity. Existing URLs, heading anchors, navigation entries, front matter, and unrelated content are preserved. No new content issues found. - The existing sidebar/SEO warnings are unchanged. The version-sync warning is intentionally explained here: the implementation targets **branch-4.2**, so only the **4.x** pages are updated. The option has not been added to the Doris master/development implementation; copying the guidance to development-version docs would claim support before that implementation exists. Other locales retain their existing content. ## Versions - [ ] dev - [x] 4.x - [ ] 3.x - [ ] 2.1 or older ## Languages - [x] Chinese - [x] English ## Docs Checklist - [x] Checked by AI: full self-review completed, including content correctness, locale/version scope, links, anchors, metadata, and example consistency. - [x] Test Cases Built: both changed MDX pages compiled; governance delta checked against the base; mode behavior was exercised in the companion implementation's native validation. - [x] Updated required version and language counterparts, or explained why not. - [x] If only one language changed, confirmed whether source/translation counterparts need sync: both English and Chinese are updated. -- This is an automated message from the Apache Git Service.
