Extended Attributes
User-defined keywords that are extracted during data classification.
Extraction Rule

Federation
A defined group of member-clusters on a Federation server that can be

fullText
The "content" portion of a file, this is the textual content of word processing
files and message content for emails. The extraction fulltext rule is used to
save file content to metadata during classifications and saves up to 10
megabytes of content by default. This default may be changed, but it is not
recommended. Fulltext extraction is required for the Previewer pane to work
and to generate Concepts in the Results Grouping pane.
Groupware
Collaborative software designed to help people involved in common tasks
achieve their goals. Incorporates services such as email, calendaring, text
chat, wiki, web-sharing, document control, and advanced search.
Hash Values
Hash values are used to compare one file with another for duplicates.
An extremely simplified description of hashing is that the numeric values of
all bytes in a file are added into a grand total. The chances of two different
files yielding the same result (hash value) are remotely small, so hash values
can be used to identify duplicate files, or compare files with the same name to
decide if they have been modified.
Computing hash on an entire file is called a full-hash, and computing hash on
a portion of the file is called a partial-hash. A "partial hash" may also be used
to increase classification speed and "hashing" can be turned on, or off to
increase classification speed.
