Search services have different functionality. One of the most convenient is the Google search engine that allows you to specify the number of additional parameters that eliminate unnecessary results.
For example, you need to find information about models of plasma TVs, but you want to exclude some brand – for example, Philips. In this case, the query would look like this: "plasma TV –Philips". Of course, the query should be entered without quotes.
If you need information about plasma televisions Philips, instead of minus, you should put a plus: "plasma TV +Philips". In this case, will be displayed that contains the name of the model.
In that case, if you need to find a specific phrase, enclose it in quotation marks. For example, if you type the phrase with quotes: “modern plasma TV”, then it displays the search results that contain this phrase. Pay attention to what must be substituted by quotation marks for Google search needs, "feet", not "Christmas trees". When you enter from the keyboard (and not via copy) is always automatically entered need quotation marks.
It may be useful to the inurl option, you can use it to search for a specific reference elements. For example, you need to find links to the online stores. In this case, you can use the query: inurl:shop.
Sometimes you need to see the list of pages of a resource. The easiest way to do this is to use the site. For example, you want to see the list of pages of the website of the Russian President http://kremlin.ru/. To do this, type in Google the following query: site:kremlin.ru view and derived search results.
Using the string "index of", you will be able to search the desired directory. For example, type in "index of" mp3 – Google will give links from relevant directories. Instead of "mp3" you can substitute you are interested in any of the row.
In that case, if you need to find some specific files – for example, with the extension *.doc, type: filetype:doc. Google will display relevant links. Note that nothing prevents you to build two types of queries, for example: filetype:doc inurl:secret – in this case vouchers in the link which contains the word secret. Not a coincidence Google is so fond of hackers – with its help they manage to find a lot of interesting information.
