The advanced search syntax can be used to find documents that have been assigned a particular tag. There is no need to specify whether you are looking for security or informational tags, since the name of each tag is unique. The syntax for this type of search is shown below.
The term Tags specifies that a search will be performed for a particular tag. The name of the desired tag is specified by the term TagName. The name of the desired tag should be enclosed by quotation marks. The following sample search will find all documents that have been assigned the tag named "NOFORN".
