## Summary
This PR fixes multiple documentation inconsistencies in the vector-search
docs around ANN `index_type` capability and parameter guidance.
## Problem
The overview pages previously stated that `index_type` only supported
`hnsw`, while Doris already supports both `hnsw` and `ivf`. This could mislead
users when choosing index algorithms.
There were also related clarity issues:
- `overview` parameter tables did not include IVF's key parameter `nlist`.
- Chinese overview pages used `metric` in one bullet while table/schema use
`metric_type`.
- Two English page titles had a typo: `Apaceh`.
## Changes
- Updated `index_type` support wording to `hnsw` + `ivf` in:
- `docs/ai/vector-search/overview.md`
- `versioned_docs/version-4.x/ai/vector-search/overview.md`
-
`i18n/zh-CN/docusaurus-plugin-content-docs/current/ai/vector-search/overview.md`
-
`i18n/zh-CN/docusaurus-plugin-content-docs/version-4.x/ai/vector-search/overview.md`
- Added `nlist` row (IVF-specific, default `1024`) to the same overview
parameter tables.
- Fixed Chinese bullet `metric` -> `metric_type` in current/4.x overview
pages.
- Fixed title typo `Apaceh` -> `Apache` in:
- `docs/ai/vector-search/ivf.md`
- `docs/ai/vector-search/hnsw.md`
## User Impact
Users now get consistent and accurate ANN capability docs, clearer IVF
parameter guidance from overview pages, and aligned EN/ZH terminology.
## Validation
- Verified diffs are limited to the six targeted documentation files.
- Re-scanned vector-search docs to confirm no remaining "only HNSW" wording
in overview capability descriptions.
