1) Boolean AND search
In this type of search, we want Web pages that contain both of our search terms that is,rain and water Boolean OR search if we want results that include either the word rain or the word snow? This calls for Boolean OR logic.
2)Boolean NOT search
Sometimes you want to retrieve documents that do not contain a particular word.
2)Combined Boolean AND, OR search
Sometimes you need a search that is more complex than a single AND or OR search.
It is possible to combine both types of Boolean logic in the same search.
3) Phrase Search and Exact Word Search
Some words naturally appear in the context of a phrase, for example, freedom of the press. To search on phrases in most search engines, simply enclose the phrase within quotes: "freedom of the press".
4)Field Search
Field searching is an optional way to focus your search results. With general search engines, you're searching the full text of many millions of pages, and field searching can help you retrieve results that may be more manageable. For example, you can search for words that appear within a particular Web site, within the URL (Web address), in the page title, and so on. The exact technique for doing this can differ among search engines, so be sure to check out the Help pages before proceeding. Let's consider a couple of examples on Google.
