Does document search work with metadata?
文档搜索可以使用元数据吗？
In document search, you search the main document which can be as small as a paragraph and as large as thousands of pages. Documents include a variety of other fields, including both unstructured text fields (title and summary), semi-structured fields (author), and structured fields (publication date, originating group, category)—the metadata. The search engine handles a mix of text and metadata in user queries.
在文档搜索中，您搜索的主文档可以小到一个段落，也可以大到数千页。文档中包含各种其他字段，包括非结构化文本字段（标题和摘要）、半结构化字段（作者）和结构化字段（出版日期、来源组、类别），即元数据。搜索引擎会对用户查询中的混合文本和元数据进行处理。
