2. If the file will contain accented characters and you have not already checked your editor's ability to
save a file with UTF-8 encoding, do so now. As an example, if you are using Notepad, do this:
• From the File menu, choose Save As.
• Check that the Save options include Encoding, as well as Name and File Type.
• Pull down the Encoding menu and choose UTF-8.
3. Edit the file as follows:
• Put one directive on each line, using the formats described under Entry format 1 and Entry
format 2, below.
• Use only alphanumeric characters and spaces, substituting spaces for hyphens. For example,
instead of entering “pro- democracy,” enter “pro democracy.” The results will include the
hyphenated version of the term. Each term can consist of multiple words separated by spaces;
the maximum number of words for each term is 4.
• Specify any number of synonyms for a particular term. There is no limit to the number of
expansions in a query.
• Use the pound sign (#) to start a comment line.
4. Save the file. If the file has accented characters, save it with UTF-8 encoding.
Entry format 1: term1 operator term2
In this format:
• term1 consists of one word or multiple words that are separated by single spaces.
• term2 consists of one word or multiple words that are separated by single spaces. operator is one of
the following:
• = Specifies that the expansion is bi-directional. The appliance expands a search query for term1
or term2 by adding the other term.
• > Causes the appliance to add term2 when a search query contains term1.
Examples:
ebu = education
business unit
tbu = telecomm business unit
telecom business unit = telecomm business unit
partner > indirect sales

ebu
is expanded to include additional documents that contain the
phrase
educational business unit
. A query where the search term in
educational business unit
is expanded to include additional documents that contain the term
ebu
. Notice that the two queries,
ebu
and
educational business unit
, are not equivalent. Also, a query where the search term is a
phrase (enclosed by quotation marks), such as
"educational business unit,"
is not expanded.

In this format:
• The curly brackets are required.
• Each term in the list will be used to expand queries for each other term.
