• All of the Words: By default, this type of search assumes that spaces between words are treated like the logical and, meaning that all of the terms entered are required to be in all of the items found. A search for
Congress economy policy would return all stories that contain all three of these words exactly as they are spelled. See the section on Wild Cards for information on including alternate spellings such as economies or economic.
• Match Any Words: This type of search assumes that spaces between words are treated like the logical or, meaning that results may contain just one of the words or possibly all of the words from your query. The search congress economy policy would return all stories containing the word congress or the word economy or the word policy. Keep in mind that this type of search can produce large search results.
• Match This Exact Phrase: This mode assumes that the space between words requires that the words be adjacent to each other and in the exact order in which you enter them. Use this type of search if you are sure the exact phrase, such as electronic banking, must occur in the stories you are looking for.
• Advanced: Boolean operators such as and, or, not and near can be used anywhere in any type of search. In the list of search types offered, the logic of the boolean connectors is used, but in some cases you do not need to enter the actual connector(s).
Instead of having spaces automatically interpreted as logical connectors, you enter the precise operators you want. You may also combine different operators in one search statement.
