 * Search Query - a word or phrase to find
 * Boolean Search - a search for an XML document that is either true or false with no ordering of search results
 * Search Hit - a match of a query to a document or document fragment
 * Hit Scoring - a method of assigning a weight to a search result for sorting. For example if a term occurs more frequently in a document it might receive a higher score
