[ ] 搜索请求失败

Error message

[%s] 搜索请求失败: %w

What it means

searchImpl wraps a doRequestWithRetry failure as "[%s] 搜索请求失败". It means the search request to daishuduanju.com failed at the transport layer or exhausted all retries — the response was never obtained.

Solutions

1. Check the wrapped cause for context.DeadlineExceeded; if so, increase searchTimeout.
2. Verify the site is reachable from your network (curl -I https://www.daishuduanju.com).
3. Retry later if the site is temporarily down or rate-limiting your IP.
4. Increase maxRetries/backoff in doRequestWithRetry for flaky connections.

results, err := plugin.Search(ctx, keyword)
if err != nil {
    if errors.Is(err, context.DeadlineExceeded) {
        // searchTimeout too short — retry with a larger timeout
    }
    return nil, fmt.Errorf("search unavailable: %w", err)
}

When it happens

Trigger: Calling the plugin search when the GET https://www.daishuduanju.com/?s=<keyword> fails in every attempt: timeout (searchTimeout context expired), DNS failure, TLS error, or connection refused/reset.

Common situations: Site is down or blocked in the user's region/ISP, anti-bot TLS fingerprinting resets connections, searchTimeout is too short for a slow network, or DNS poisoning of the domain.

Understand the failure class

Background: 'Something went wrong' / 'Request failed (500)' / 'HTTP error! status: 404' — what failed HTTP requests actually mean and how to find the real cause — this error's family across 28 libraries.
