Multiple WordsPhrase Searches
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
Search for complete phrases by enclosing them in quotation
marks. Words enclosed in double quotes will appear together in all results
exactly as typed.
- * 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
The '*' wildcard may also be embedded in a search string. For
example, "colo*r" would match both "color" and "colour".
- ** Matches any number of non-space characters, starting
at the specified position in the word. For example, "comput**" will match all
words that begin with "comput" (e.g., "computer", "computation", etc.).

- ? You may use a question mark ('?') to replace a single
character anywhere within a word.
Use AND or OR to specify multiple words in any field, any
order. Use AND NOT to exclude words. Select the operator you wish to use from
the selection list on the Advanced Search form.Proximity Operators

the specified words or phrases within ten words of each other in the same
indexed field. 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.
Field limits may be specified by selecting a field limit
from the selection list in the form above. These limits appear before the word
or phrase to be searched. A field limit causes the system to search only the
specified field for the specified word(s).
Keyword search results are usually grouped by relevance to
bring the most likely titles to the top of the list. Each group represents a
similar level of relevance and results are sorted within the group by date or
title. To get an ungrouped result set, use boolean operators to form a complex
