Najpopularnija "mašina" za traženje na netu, Google može postati mnogo efikasnija ako koristimo neke od trikova:

01. Što smo detaljniji u traženju dobit ćemo bolje razultate. Ovdje važi pravilo da se traže specifične riječi, koje upravo očekujemo da ćemo naći na željenoj stranici, i koju ne možemo vidjeti na mnogo drugih stranica.
Ako npr. tražimo riječ CATS ne koristi nam ništa ako samo upišemo riječ 'cats' u polje za traženje i pritisnemo enter. Umjesto toga bi možda bilo bolje da tražimo " cats musical". Neuspjela potražnja se uvijek može spasiti dodavanjem više riječi. U našem slučaju recimo, ako znamo da je "Cats" napisao Andrew Lloyd Webber, onda možemo u polje za traženje dodati 'Webber'. Google ne pravi inače razliku izmedju malih i velikih slova.

02. Upotrebom navodnika na početku i kraju više riječi, ograničavamo traženje na riječi (ili rečenice) koje se na stranicama pojavljuju baš ovim redoslijedom.

03. Minus znak se koristi ako odredjenu riječ ne želimo vidjeti u rezultatima potrage. Ako npr. tražimo riječ SPAM (koja je u vezi sa lošim mesom), i ako nismo zainteresovani za stranice koje opisuju spam-mails i kojih ima mali milion na internetu, onda bi u polju za traženje trebalo da stoji 'spam -mails'. Riječ će samo biti izostavljena u slučaju da stoji prazno mjesto i minus odmah ispred riječi koja se želi izostaviti.

04. Trebamo takodje uzeti u obzir da Google ignoriše neke riječi, slova i brojeve, koji se pojavljuju jako često. Ipak Google se može prisiliti da traži ove podatke, tzv. "stop-riječi" i to dodavanjem + znaka ispred ovih pojmova.
Nema svrhe recimo tražiti riječ 'Pentium 4', jer će znak 4 biti izostavljen automatski. U ovom slučaju moramo upisati 'Pentium +4' ili još bolje "Pentium 4" (uz upotrebu navodnika).

05. Kada tražimo više riječi, Google traži sve te riječi koje se pojavljuju u polju za traženje. Tražilica takodje razumije i OR značenje, što će nam pomoći u traženju pojmova koji se različito pišu ali predstavljaju isto. Npr. traženjem riječi - - -"H. C. Andersen" OR "HC Andersen" - - - dobit ćemo sve stranice koje sadrže jedan ili drugi pojam.

06. U traženju cijelih rečenica jako nam pomaže JOKER znak - * , koji bi trebao biti zamjena za neku riječ.
Ako npr. želimo znati koje je srednje ime danske princeze  , onda bi trebali tražiti "mary * donaldson" i dobit ćemo odgovor. Ako smo u nedoumici za više riječi možemo koristiti nekoliko joker znakova. Na google se ne može koristiti joker znak za završetak neke riječi, jer u tom slučaju google traži gramatičke varijante tražene riječi.

07. Google-u bi trebalo biti svejedno da li se koriste akcenti ili diakritički znakovi, ali to nije slučaj.
Prilikom traženja riječi "Göteborg" nećemo dobiti iste rezultate kao pri traženju "Goteborg" ili "Gøteborg". "Göteorg" i "Goeteborg" se tretiraju isto, kao i "Düsseldorf" i "Duesseldorf" ali ne i "Dusseldorf". U ovim slučajevima bi se trebalo tražiti više riječi da biste dobili što detaljniji rezultat.

08. Ako poznajete dobro engleski ali ne i ostale evropske jezike, možete koristiti google prevodioca. Može se koristiti za prevodjenje stranica ili dijelova teksta sa njemačkog, španskog, talijanskog, francuskog ili portugalskog na engleski jezik. Takodje može se prevoditi i obratno, njemački na francuski npr. Ovo prevodjenje je jako "sirovo" i "falično" ali u svakom slučaju može poslužiti svrsi razumijevanja tekstova.
Google-ov prevodilac se može naći na adresi http://www.google.com/language_tools?hl=en" target="_blank
Dobra alternativa ovom prevodiocu je AltaVista Babel Fish. Naći ćete je na http://babelfish.altavista.com" target="_blank

09. Moguće je koristiti google kao digitron ili konverter. On poznaje mnoge mjerne jedinice ali razumije samo engleski, tako da bi bilo poželjno tražiti na sljedeći način '17 inches in centimeter' i dobit ćemo odgovor da je to 43,18 cm.

10. Takodje je moguće koristiti google za traženje u okviru odredjenog vremenskog perioda kao i odredjene tipove fajlova.
Ovi su parametri naznačeni na stranici http://www.google.com/advanced_search
Ovdje možete google-u "objasniti" da ste zainteresovani za stranice koje su indeksirane u zadnjih 3, 6 ili 12 mjeseci, kao i da ste zainteresovani za rezultate odredjenog domena i odredjenog tipa fajla, kao i jezika.

Google’s Advance Search Query Syntaxes

Below discussed are various Google’s special commands and I shall be explaining each command in brief and will show how it can be used for critical information digging.

[ intitle: ]

The “intitle:” syntax helps Google restrict the search results to pages containing that word in the title. For example, “intitle: login password” (without quotes) will return links to those pages that has the word "login" in their title, and the word "password" anywhere in the page.

Similarly, if one has to query for more than one word in the page title then in that case “allintitle:” can be used instead of “intitle” to get the list of pages containing all those words in its title. For example using “intitle: login intitle: password” is same as querying “allintitle: login password”.


[ inurl: ]

The “inurl:” syntax restricts the search results to those URLs containing the search keyword. For example: “inurl: passwd” (without quotes) will return only links to those pages that have "passwd" in the URL.

Similarly, if one has to query for more than one word in an URL then in that case “allinurl:” can be used instead of “inurl” to get the list of URLs containing all those search keywords in it. For example: “allinurl: etc/passwd“ will look for the URLs containing “etc” and “passwd”. The slash (“/”) between the words will be ignored by Google.


[ site: ]

The “site:” syntax restricts Google to query for certain keywords in a particular site or domain. For example: “exploits site:hackingspirits.com” (without quotes) will look for the keyword “exploits” in those pages present in all the links of the domain “hackingspirits.com”. There should not be any space between “site:” and the “domain name”.


[ filetype: ]

This “filetype:” syntax restricts Google search for files on internet with particular extensions (i.e. doc, pdf or ppt etc). For example: “filetype:doc site:gov confidential” (without quotes) will look for files with “.doc” extension in all government domains with “.gov” extension and containing the word “confidential” either in the pages or in the “.doc” file. i.e. the result will contain the links to all confidential word document files on the government sites.


[ link: ]

“link:” syntax will list down webpages that have links to the specified webpage. For Example: “link:www.securityfocus.com” will list webpages that have links pointing to the SecurityFocus homepage. Note there can be no space between the "link:" and the web page url.

 related: ]

The “related:” will list web pages that are "similar" to a specified web page. For Example: “related:www.securityfocus.com” will list web pages that are similar to the Securityfocus homepage. Note there can be no space between the "related:" and the web page url.


[ cache: ]

The query “cache:” will show the version of the web page that Google has in its cache. For Example: “cache:www.hackingspirits.com” will show Google's cache of the Google homepage. Note there can be no space between the "cache:" and the web page url.

If you include other words in the query, Google will highlight those words within the cached document. For Example: “cache:www.hackingspirits.com guest” will show the cached content with the word "guest" highlighted.


[ intext: ]

The “intext:” syntax searches for words in a particular website. It ignores links or URLs and page titles. For example: “intext:exploits” (without quotes) will return only links to those web pages that has the search keyword "exploits" in its webpage.


[ phonebook: ]

“phonebook” searches for U.S. street address and phone number information. For Example:  “phonebook:Lisa+CA” will list down all names of person having “Lisa” in their names and located in “California (CA)”. This can be used as a great tool for hackers incase someone want to do dig personal information for social engineering.
