Bing自定义搜索MetaTags格式疑问：search.date字段解析异常

It’s a bit confusing when the API returns that split format without explicit documentation, but this is actually Bing’s internal structured parsing behavior for date-type meta tags like search.date. Here’s a clear breakdown of what’s going on:

• Escaped original content: The first segment "22\/05\/2018 00:00:00" is a standardized escaped version of your original meta tag’s content. The \/ is a standard JSON escape for forward slashes, and " is the HTML entity for double quotes—Bing wraps the raw content in quotes and escapes it to preserve the original string exactly as it appeared in your meta tag.
• Structured date components: The semicolon-separated values (22; 05; 2018; 00; 00; 00) are Bing’s automatic parsing of the date/time string into individual, usable components: day, month, year, hour, minute, second. This is a behind-the-scenes optimization specifically for search.date (a search-focused meta tag), as it lets the engine (and you) work with granular date parts for filtering or semantic search operations, even if you only provided a single combined string in your meta tag.

While this behavior isn’t called out in the official API docs, it’s a common pattern for search engines handling structured metadata—they often preserve the raw value and extract structured fields to offer more flexibility to developers. You can choose to use the full escaped string if you need the original format, or parse the semicolon-separated values if you need to work with individual date/time parts.
