An Expert Search lets you do a precision search using a combination of
keywords, search categories, search operators, and parentheses.
- Select a database to search.
- Type your search terms in the text box labelled Search Terms.
A search term, or query string, is a line of text that consists of a combination of:
- Search Categories
- Boolean Operators
Keywords are words found in any field that has been indexed for searches.
With keywords, you can specify left, right, or medial truncation and
wild card searches.
Example: Use an asterisk (*) to designate one or more characters:
Ho* Virtua will find hose, host, hostess, etc.
Wa*n Virtua will find walton, warden, Washington, etc.
Example: Use a question mark (?) to designate a single character.
Use two question marks to designate two characters, and so forth:
Ho? Virtua will find hop, hog, hot, etc.
Wa?n Virtua will find warn
w??en Virtua will find women, woven, Woden, etc.
pa: personal name
ca: corporate name
tse: series title
pp: place of publication
aw: anywhere (ALL indexed fields)
nc: nature of content
Note: Capital or lower case letters can be used for designating
- AND NOT
&xx Proximity, where x is a number that represents the number
of characters between the search words.
Example: t:cat &3 t:behavior
will find Cat within 3 characters of the term
behavior in any title. The search string would return:
Notes concerning proximity searching
- It is possible within ONE category only.
- It is possible between TWO terms only.
- The search operator OR has no inherent value in a proximity search
between two terms. Use OR only in a query string that contains parentheses.
- For a combination of terms, there is not operator precedence.
You can use parentheses anywhere within a query string to set precedence.
Example: To find books by either Richard Bachman or Stephen
King, you might use parentheses with each string query. If parentheses are not
used, the software will apply operators from left to right.
(a:richard & a:bachman) + (a:king
