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.
