## Overview

V2EX (www.v2ex.com) is a long-standing Chinese developer community centered on programming, career, products, and niche technical discussion. This channel queries sov2ex.com, a third-party ElasticSearch-style search index over V2EX threads.

## When to Choose It

- Choose it for Chinese developer-scene queries (programming opinions, framework tradeoffs, career discussions, niche troubleshooting).
- Choose it when the query implies programmer-audience in Chinese discourse but zhihu is too broad and weibo is too noisy.
- Avoid for academic, multimedia, or general consumer lifestyle queries.

## How To Search

- `api_search` — Queries `https://www.sov2ex.com/api/search?q=<q>&size=10`. Extracts threads from `hits[*]._source` and constructs canonical thread URLs as `https://www.v2ex.com/t/{id}`.

## Known Quirks

- sov2ex.com is a third-party index, not V2EX's official search. Index freshness depends on that operator; thread titles/bodies are usually current but index lag can be hours.
- V2EX itself has no public search API — the site relies on external indexes or Google site-search. This channel picks sov2ex as the most stable JSON option.
- Developer community, so Chinese + English code snippets mix naturally in content. Language tag is `[zh, mixed]`.

# Quality Bar

- Evidence items have non-empty title and url.
- No crash on empty or malformed API response.
- Source channel field matches the channel name.
