The OLS search options correspond to fields in
the various databases. To search for items with
information in a particular field, use the
following two-letter options:
AU
CL
Enter the author's whole name, or if the
author's complete name is not known,
users may search with the surname, first
name, or initials. Format is irrelevant;
OLS searches all parts of the name
separately.
The format of the call number depends
on the way it was originally entered; call
numbers vary from one database to
another within O.LS. It is always wise to
end the call number search with a
wildcard character "*". (See Search
Tip®.) '
OLS searches all corporate source fields.
Enter a whole or partial name.
Enter a keyword or phrase which will be
searched in all title, subject and abstract
fields simultaneously. Use quotation
marks if the phrase includes spaces.
Enter the entire number, if known. Enter
only the beginning letters of the report if
searching for all reports from a specific
agency. Spaces and punctuation may be
omitted, it is'wise to use a wildcard
character "*" at the end of the search
statement. (See Search Tip ©.)
Enter a word, phrase or complete title,
without articles such as "a" or "the". Use
quotation marks if the phrase includes
spaces.
Enter a four-digit publication year. It is
possible to use a wildcard character "*",
but the resulting search will be
extremely slow. (See Search.Tip ©.)
* Search options for individual databases may vary.
Use HELP screens to see search strategies
cs
KY
RN
TI
YR
€J Use the wildcard character "*" to truncate a
word or phrase.
Example: TI = 'Hazard
© Search numbers without leading zeros.
Example: FIND "OCLC = 514174"
© Search strings containing blanks MUST be
enclosed in double quotation marks.
Example: "John muir" or "QH104.M851988"
© You may search for year of publication in
the format YYYY for a specific year, or
. YYYY:YYYY for a range of years.
Example: YR = 1990: YR = 1989:1991
© When searching numeric fields such as the
year of publication, you can search for a set
of values defined by the following logical
operators: Greater Than (GT); Less Than-
(LJ): Greater Than or Equal to (GE); or Equal 1
to (EQ).
© You may "stack" some commands. .
Example 1: H TI H AU will provide information ;|
on Title searching.and then on author
searching without returning to the Patron
Menu in between.
Example 2: TI = "silent spring" will begin the
search with one step.
© When searching using call numbers, it is
wise to end the search with a wildcard "*"'
because not all call numbers include the
date.
Example: CL=QH104*
© When searching report numbers, spaces and ,|
punctuation marks may be omitted from
the search request. It is useful to use the
wildcard "*" as the last character in the
request,
Example: eoo r 93015*
