Documents, crm-systems and e-mail servers may be a valuable source for meta-data, such as author, source, project etc. This meta-information can be saved with each document and used for filtering. We have had support for meta-information in the core search kernel for some time, and you have probably used it to filter on dates and file types.
In v2.1 meta-information has been extensively expanded, and almost every document now has some kind of metadata. The first thing you'll notice is the more advanced filtering menu on the left of the search interface. The default menu will show document types subdivided into file formats, information type for particular useful meta-data, and date of creation.
On the search results page we now display who emails are to and from. You may click on the email address to filter on it. Clicking on the magnifying glass lists all emails from this email address.
On some documents, selected meta-information will be shown in the snippet, too.
It is also possible to search for specific meta-information. For instance, the query 'attribute:"author"' will return all documents with an author set, and the query 'book attribute:"author=John Doe"' will return all documents of the specified author containing the word 'book'.
