Summary: Most knowledge staff know a little about Boolean searching. However, as the world’s largest search engine only has limited support for Boolean operators, most law firm users do not appreciate they have this capability in their knowledge system. Sysero automatically adds an OR between words when searching meaning that results may contain any of the words in the search. By typing an AND in uppercase between the search words, the number of results is reduced significantly as each result must contain all the words. However, the real power is using the NOT operator. This can be used to remove all the results contain a specific word or phrase and can be invaluable when finding that needle in the haystack.
