Document Meta-Data Tag
This tag identifies a block of meta-data for a matching document. This tag has the form:
<meta>
…
</meta>
The actual tags within the meta-data block will depend on the implementation of the
Pre-Filter used by the textIndexer. However, any matches found in the meta-data will be marked with
Snippet or
Hit tags, depending on what the query specified (snippets by default.).
The document meta-data tag is always included in the query results, regardless of whether there are any matches in it or not. This guarantees that the result formatter has access to the title of the document and other document related information in addition to the match results.
