Searches are not case-sensitive. For example, the terms smile, SMILE, sMiLe, Smile, or smilE all produce the same results.
To search for variations of a term, use the * as a wildcard. For example, type smil* to search for smile, smiling, smily etc.
Words are stemmed, i.e., variants of words that indicate plurality or verb tense are equivalent. For example, a query of talked produces results that match talks, talking, and talk as well.
Combining Terms
When you type terms in more than one field, results contain articles that match all fields. For example, if you type a term in the Author field and in the Title field, only articles that contain both terms appear in the results.
When you type more than one word in a field, results contain all terms. For example, the search father child produces the same result as typing father and child; it retrieves articles with both terms in the field.
To search for either term in a field, type OR between them. For example, the search father or child retrieves articles with either term in the field.
To search for one term and not another in a field, type NOT between them. For example, father NOT child retrieves articles with father, but NOT child.
