In the above example, the words product and price might be included in the search results. However, the word widget must occur in each hit. The plus sign is also used with quotation marks to require a phrase. However, the minus operator does not necessarily exclude terms altogether. Terms that are marked with a minus operator will receive the lowest rank in search results.
Field searches A field search is a search that looks for certain elements within a document.
However, the user only wants documents returned which contain that phrase in the title. Documents containing the phrase in the body or elsewhere should be ignored. The user can also use the Advanced Search form to create the query, in which case he need not know the exact syntax to create the search. Searches by document title You can search for an HTML document s title by typing all or part of a title as your search query. The above example yields the most narrowed pool of search results.
