Error message

[%s] 获取搜索结果失败: %w

What it means

xdpan's searchImpl wraps any error from fetchSearchResults with the plugin name prefix: '[xdpan] 获取搜索结果失败: %w'. It is a top-level aggregation point — the root cause is one of the wrapped errors inside fetchSearchResults (request creation, transport failure, non-200 status, Cloudflare challenge, or HTML parse failure).

Solutions

Unwrap the chained error (%w) to find the root cause and fix that specific failure first.
If the root cause is the Cloudflare challenge, wait, change network/IP, or update cookies before retrying.
Check the configured baseURL is reachable (curl the /search?page=1&k=... endpoint directly).
Retry with backoff for transient network/5xx root causes.

Defensive patterns

Strategy: try-catch

Try / catch

results, err := pluginSearch(keyword)
if err != nil {
	// unwrap the chain to reach the root cause
	root := err
	for errors.Unwrap(root) != nil { root = errors.Unwrap(root) }
	log.Printf("xdpan search root cause: %v", root)
}

Prevention

Always inspect the wrapped root cause, not the top-level message.
Detect the Cloudflare 'Just a moment...' condition early and back off.
Keep the baseURL configuration validated and current.

When it happens

Trigger: Any failure in fetchSearchResults during a xdpan search: malformed search URL, network/DNS/timeout on the GET, non-200 response, 'Just a moment...' Cloudflare challenge page, or goquery parse error. searchImpl then re-wraps with the plugin name.

Common situations: The xdpan site is behind Cloudflare and serving browser verification to datacenter IPs; the site is down or moved; keyword contains characters that break the query string; rate limiting after frequent searches.
