Back then, the notion of Boolean search referred to the use of terms like OR, AND or NOT to increase the effectiveness of a query. When this all began, more than 20 years ago, using search to solve problems was a novelty. The search develop* would return results with any of the following words: develops, developer, developers, development, developments, developing Asterisk * (or Wildcard) allows the search to contain the stem of a word.i.e., (Java OR C++ OR Ruby OR JavaScript) Parentheses (_) are especially useful with long strings of OR queries.Without the quotes, the search results contain documents with those words anywhere, not necessarily next to each other The search query “baseball player” returns documents with those two words together. Quotation Marks “_“ mean that the search engine should treat the words inside of the quotation makes as a single search term.In addition to these core operators, Boolean includes powerful modifiers The search results will include the first term and will exclude results that contain the second term. NOT means that the following term should be excluded from search results.i.e., Java AND C++Īll search results will include both terms. AND means that the search results should include both terms.You can make long strings of OR to make sure that a large range of terms are included. The search results will include either of the two terms but not necessarily both. i.e., MBA OR Masters of Business Administration
