Here is the step-by step process for building this search:

- the "key" words in the search, including synonyms (that is, words with the same meaning) are:

higher education, colleges, universities

cost, tuition,  fee

- the boolean connector "OR" will combine terms with similar meanings:

higher education or colleges or universities

cost or tuition or fee

- need to use parenthesis, (     ), around the terms combined with the "OR":

(higher education or colleges or universities )

(cost or tuition or fee)

 - need to use the boolean connector "AND" to combine and require terms to appear in the results:

(higher education or colleges or universities) and (cost or tuition or fee)

- need to use truncation, *, to get different word endings, such as both singular and plural:

(higher education or college* or universit*) and (cost* or tuition or fee*)

- need to use quotations, "  ", for phrase searching:

("higher education" or college* or universit*) and (cost* or tuition or fee*)

Below are two example of other, simpler searches on the same topic.  Note how these two searches provide fewer results than the search above since they do not include all possible synonyms (that is, words with the same meaning) :

1. higher education and cost*

2. (college* or universit*) and cost*
