Boolean Search Instructions

Enter a search command using Common Command Language (CCL). You can combine search terms with And, Or, Not to build complex searches.

And - A record must match both the term before and the term after the operator to be included in the search results.
Example: AU=isaac asimov AND TI=planets
Finds only the items written by Isaac Asimov that have the word planets in the title.

Or - A record can match either the term before or the term after the operator, or both, to be included in the search results.
Example: AU=isaac asimov OR TI=planets
Finds all items written by Isaac Asimov and all items with the word planets in the title by any author, including Asimov.
If you have a number of terms to combine with OR, type the command this way:
AU={list}asimov, dick, ballard, lem, capek{/list}
You can insert as many terms as you need between {list} and {/list}

Not - A record must match the term before the operator, but not the term after the operator, to be included in the search results.
