Operators are connectors between words used in searching a database. For example AND, OR, NOT are Boolean operators.
Used in a search to combine search criteria. The valid operators are: the ampersand (&), the vertical bar (|), and the caret (^) (for combining search terms). Unless you use them as part of a phrase, the search engine ignores the words AND, NOT, and OR and other words that occur so often in typical writing that they provide no search value to the search engine or the user. The search terms you can combine in your search criteria include: individual words, terms with wildcard characters, phrases, and search terms in proximity.
Commands that are used to combine keywords to broaden or narrow the results of a search. Combining terms using operators is sometimes called Boolean searching. Boolean operators are the words AND, OR, NOT, which are used to connect search terms. AND narrows a search by requiring that both terms be present. OR broadens a search by incorporating synonyms or alternate terms. NOT narrows a search by excluding terms. Most databases include other operators, but AND, OR, NOT are the three that will always work.
Terms that allow you to link keywords together to expand or refine a search (commonly AND, OR, NOT). You might also hear them referred to as "Boolean operators". password A string of characters from the computer keyboard selected by a user to authenticate them when they log on.
