Message Indexing
Before a message enters the archive, Message Archiving indexes of the
keywords (significant or meaningful words) in all parts of the message, including
the body text, Subject line, and headers. It also indexes keywords in most types of
file attachments that include text, such as Microsoft Office documents, PDF files,
text files, and HTML pages. Message Archiving does not, however, index
common words such as articles (for example, the, that, and an), prepositions (for
example, to, in, and on), and conjunctions (for example, and, or, and so).
A message’s index is a map of its content, and specifies in which part of the
message each keyword appears, for example, in the body, Subject line, To or
From field, headers, or attachments.
When you initiate a search, Message Archiving checks the indexes for matches to
the keywords you enter rather than checking the full contents of each message
and attachment identified by your criteria, thereby reducing the retrieval time.
