未找到搜索结果页面重定向信息

Error message

未找到搜索结果页面重定向信息

What it means

xb6v's search protocol relies on the search POST returning a redirect (Location header, JS location.href, meta refresh, or a result/?searchid=... URL). When no Location header is present, the plugin parses the body with three regex strategies; if none yields a redirect target, it throws this error, meaning the expected redirect flow was not followed.

Solutions

Try a different keyword; a rejected/empty search often produces a non-redirect error page.
Verify the configured mirror base URL is current — outdated mirrors commonly break the redirect flow.
Enable debug mode to dump the first 500 chars of the response body and confirm what the site actually returned (captcha/error page vs layout change).
Update the plugin's extraction regexes if the site changed its redirect format (e.g. new parameter name instead of searchid).

Defensive patterns

Strategy: fallback

Validate before calling

// sanity-check keyword before searching
kw := strings.TrimSpace(keyword)
if kw == "" { return errors.New("keyword is empty") }

Try / catch

results, err := pluginSearch(keyword)
if err != nil && strings.Contains(err.Error(), "未找到搜索结果页面重定向信息") {
	// treat as 'site flow changed or no results' — try alternate plugin/mirror
	results, err = fallbackPlugin.Search(keyword)
}

Prevention

Keep mirror base URLs up to date; test them periodically.
Retry with a simplified keyword when a search yields no redirect.
Monitor for site template changes if you depend on this plugin.

When it happens

Trigger: The POST to /e/search/index.php succeeds (HTTP response received) but contains no Location header and the body contains none of: location.href assignment, href/url= with searchid, or result/?searchid=N pattern — e.g. the site returned an error page, a captcha, a 'no results' page, or changed its redirect mechanism.

Common situations: The xb6v mirror changed its search backend and no longer emits searchid redirects; the search keyword was rejected and an error page was returned; the site is behind anti-bot protection serving a challenge page; site template update removed the JS/meta redirect.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
