1. What is Advanced Search?Advanced search enables increased accuracy of search results by using additional syntax to focus the search. One or more search criteria or operators can be combined in order to tailor the results more specifically towards your needs. These operators allow you to find what you're looking for quickly and accurately. For Search Engine Optimizer’s (SEO’s), advanced search operators are essential if you want to ‘peek under the hood’ by doing a much deeper and more accurate web searches.

2. Advanced Search OperatorsThe following 4 search operators are widely known on most search engines and can be used to adjust search results to your current needs:

-Excludes the keyword from the search results

e.g., loans -student shows results for all types of loans except students' ones

+Allows for a forced keyword inclusion (especially useful for including stop

words)e.g., Seo +for

" ”Shows search results for the exact phrase

e.g., "Seo Company"

ORShows results for at least one of the keywords

e.g., Google OR Bing

3. Google Search QueriesThe following table lists which search operators work best with each Google

Search Service.

4. Boolean Search Logic

Boolean Searching on the Internet

Boolean logic consists of three logical operators: NOT, AND & OR. Each operator can be visually described by using Venn diagrams, as shown below.

OR logic:

Most commonly used to search for synonymous terms or concepts. The more terms or concepts we combine in a search with OR logic, the more results we will retrieve.

E.g. college OR university OR Campus

AND logic:

In this search, we retrieve records in which BOTH of the search terms are present. The more terms

or concepts we combine in a search with AND logic, the fewer results we will retrieve. E.g. poverty

AND crime AND gender

NOT logic:

In this search, we retrieve records in which ONLY ONE of the terms is present, the one we have selected by our search. NOT logic excludes records from your search results. Be careful when you use NOT: the term you do want may be present in an important way in documents that also contain the word you wish to avoid.

E.g. Cats NOT dogs

This is illustrated by the shaded area with the word cats representing all the

records containing the word "cats" with no records are retrieved in the area

overlapping the two circles where the word "dogs" appears, even if the word

"cats" appears there too

.

Combined AND & OR logic:

You can combine both AND & OR logic in a single search. The use of parentheses in this search

is known as forcing the order of processing. In this case, we surround the OR words with

parentheses so that the search engine will process the two related terms as a unit. The search

engine will use AND logic to combine this result with the second concept. Using this method, we

are assured that the semantically-related OR terms are kept together as a logical unit.
