Search engine techniques are important in order to get the most accurate results from your searches. These include searching for exact words and phrases, using boolean operators, finding missing words in a phrase, searching with multiple keywords and narrowing the time frame for your search results. These search engine tricks are easy to use and will give you the best results.

The basic functions of a search engine are crawling, data mining, indexing and query processing. The crawler-based search engines send small programed bots out to collect web pages and save them on the server in a kind of book called an index. This index is refreshed regularly, usually every month or two, to reflect any new information that may have been added to the website since it was last indexed.

Once the search engine has compiled the information in its database, it is ready to perform a person’s search. The user enters a query into the search box, and this is then processed mathematically by the search engine to determine what indexed terms are most relevant to that query. The results are then returned to the searcher.

When performing a search, you can narrow your results by including quotation marks around your desired search terms. This will make sure the search engine recognizes that you want to find exactly that phrase, and ignores other similar words. It is also possible to exclude certain types of words from the results, such as the, and, or, and of, which are often considered as filler words by the search engine and are not ranked very highly.

You can use boolean operators to refine your search by adding and or, not or, and or, and, or, to the terms you are searching for. The AND operator will return documents that contain all of your search words, and the OR operator will broaden the search by allowing the search engine to consider any document that contains either of your search terms.

Adding the tilde to your search can also expand it by matching synonyms of the term you are looking for. This is useful when trying to find information on the same topic from a variety of different sources.

Another way to narrow down your search is by using the wildcard * charachter in your search. This will replace any word that is not important to your search with a relevant one. This is useful if you have mistyped a word or the search engine is over-zealous in capitalizing the word.

You can also use parentheses to group your search terms together. The search engine will first look for the term inside the parenthesis, and then it will search for each individual word in the phrase separately. This can help you narrow your search and save time. You can even use this technique to search PDF documents. To do so, place the text &tbs=qdr:h at the end of the search result URL. This will make Google search your result by time period.
