Boolean Search String Hints



Boolean Searches allow you to zero in on the jobs most interesting to you. Here are the most common Boolean parameters used.


1.      And - Example: Java and Oracle. Both words must be used in the job order key words or description fields.

2.       Or - Example: Oracle or Java. Either word must be used.

3.       Parenthesizes - Example: Oracle and (cold fusion or asp). This string will give you job orders with oracle and either in cold fusion or asp.

4.       Asterisks - Example: Network Admin*. This will give you job orders with either network administration or network administrator as key words.

5.       And Not - Example: Oracle and not dba.


Advanced Search Made Easy

You can increase the accuracy of your searches by adding operators that fine-tune your keywords. Most of the options listed on this page can be entered directly into the Google search box or selected from Google's Advanced Search page.

Additionally, Google supports several advanced operators which are query words that have special meaning to Google. For a complete list, click here.

Advanced Search
" + " Searches

Google ignores common words and characters such as "where" and "how", as well as certain single digits and single letters, because they tend to slow down your search without improving the results. Google will indicate if a common word has been excluded by displaying details on the results page below the search box.

If a common word is essential to getting the results you want, you can include it by putting a "+" sign in front of it. (Be sure to include a space before the "+" sign.)

Another method for doing this is conducting a phrase search, which simply means putting quotation marks around 2 or more words. Common words in a phrase search (e.g., "where are you") are included in the search.

For example, to search for Star Wars, Episode I, use:

Bottom of Form

" - " Searches

Sometimes what you're searching for has more than one meaning; "bass" can refer to fishing or music. You can exclude a word from your search by putting a minus sign ("-") immediately in front of the term you want to avoid. (Be sure to include a space before the minus sign.)

For example, to find web pages about bass that do not contain the word "music", type:

Top of Form

Bottom of Form

" ~" Searches

You may want to search not only for a particular keyword, but also for its synonyms. Indicate a search for both by placing the tilde sign ("~") immediately in front of the keyword.

For example, to search for food facts as well as nutrition and cooking information, use:

Top of Form

Bottom of Form

Phrase Searches

Search for complete phrases by enclosing them in quotation marks. Words enclosed in double quotes ("like this") will appear together in all results exactly as you have entered them. Phrase searches are especially useful when searching for famous sayings or proper names.

"OR" Searches

Google supports the logical "OR" operator. To retrieve pages that include either word A or word B, use an uppercase OR between terms.

For example, to search for a vacation in either London or Paris, just type:

Top of Form

Bottom of Form

Domain Restrict

If you know the website you want to search but aren't sure where the information is located within that site, you can use Google to search only that domain. Do this by entering what you're looking for followed by the word "site" and a colon followed by the domain name.

For example, to find admission information on Stanford University's site, enter:

Top of Form

Bottom of Form

Numrange Searches

Numrange can be used to specify that results contain numbers in a range you set. You can conduct a numrange search by specifying two numbers, separated by two periods, with no spaces. Be sure to specify a unit of measure or some other indicator of what the number range represents.

For example, you might conduct a search for DVD player $250..300 or 3..5 megapixel digital camera. Numrange can be used to set a range for everything from dates (Willie Mays 1950..1960) to weights (5000..10000 kg truck).
