| Multiple Words |
When searching multiple words the
system will automatically supply the Boolean "and" operator between
each word; multiple words entered for the search will all occur somewhere
in the retrieved records though not necessarily in the order entered. Both
examples on the right will retrieve the same results. |

for complete phrases by enclosing them in quotation marks. Words
enclosed in double quotes will appear together in all results exactly
as typed. |

| Wildcards |
| * |
The asterisk ('*') matches
up to five non-space characters, starting at the specified position in
the word. For example, "inter*" will match "internal" and "internet",
but will not match "international". The '*' wildcard may only appear
after at least two characters.
The '*' wildcard may also be embedded in a search string. For example, "colo*r" would match both "color" and "colour".
|
environment* polic*
|
| ** |
Matches any number of non-space characters, starting at
the specified position in the word. For example, "inter**" will match
all words that begin with "inter" (e.g., "internal", "internet",
"international", etc.).
The '*' wildcard may also be embedded in a search string.
|
comp**
|
| ? |
You may use a question mark ('?') to replace a
single character anywhere within a word. |

The WITHIN operator is similar to the NEAR operator, but
allows the user to specify the maximum number of words that may appear
between the specified words. WITHIN 10 and NEAR are equivalent.
