Boolean operators such as the terms AND, OR and NOT are helpful when trying to obtain more focused results. Proximity operators can also help searchers to find words next to or close to one another. Typically the terms that are used for this type of search are WITHIN and NEAR. Other useful search operators include truncation and wildcards. Truncation uses the root of the word and then searches for all endings of the word. Wildcards allow one to replace letters within a word with symbols.
