density of the search term in the searched documents. The more frequent the
occurrence of a word in a document, the higher the document’s score.
As a result, the search engine ranks documents according to word density as it searches
for the word you specify, as well as words that have the same stem. For example,
"films," "filmed," and "filming" are stemmed variations of the word "film." To search
for documents containing the word "film" and its stem words, you can enter the word
"film" without modification. When documents are ranked by relevance, they appear in
a list with the most relevant documents at the top.
Explicit syntax
When you use explicit syntax, the search engine interprets the search terms you enter
as literals. For example, by entering the word "film" (including quotation marks) using
explicit syntax, the stemmed versions of the word "film", "films," "filmed," and
"filming" are ignored.
