Help with Acorn
In general, use keyword to search for concepts or for specific items when you do not have complete title or author information.
Keyword searches may be entered on either the Basic Search page or the Advanced Search page.
Basic Search offers: use of Boolean and positional operators, truncation and nesting of search phrases; the option to limit searches to one field; the option to limit searches to the holdings of one library.
Advanced Search offers: all of the Basic Search features above, plus a guided search form; options for limiting searches to a combination of fields; options for limiting searches by publication year, language and library; options for sorting results.
Designate a set of terms as a phrase by enclosing the expression in single quotes. This enclosed search expression must be matched in the catalog exactly as typed.
The symbol for a single character is ?; for multiple characters use $. If you follow the $ symbol with a number, Unicorn limits the number of characters matched.
To literally search these symbols/characters, enclose them with double quotation marks.
At least one character must precede the symbol.
If you type more than one word into the search box, Acorn searches for the words in the SAME FIELD of the Acorn record.
To change the search strategy, combine words with one of these Boolean or proximity operators:
When the search expression consists of a combination of terms, the order in which these terms are searched can be defined. If two operators are at the same level in the list, Acorn first searches the term at the left, then moves right. Refer to the following list for operator precedence, with the highest listed first.
Group or nest search expressions using parentheses. Acorn searches the expression located in the innermost set of parentheses first. Acorn continues the search, moving outward to the terms at the edges of the expression.
These words are excluded from all keyword searches unless enclosed in double quotation marks: a, an, and, as, at, be, but, by, do, for, if, in, is, it, near, not, of, on, or, same, the, to, with.
