addDomainAndRange ( List predicateList ) : List	takes the list of Predicates and add tothem the domain and Range data needed in two steps 1st : searching for direct Domain and ranges 2nd : searching for predicates who don't have domain and ranges and select the all predicates and objects get their types and add them to the domain and range field
scoreLiterals ( List results, int n ) : List
scorePredicates ( List results, int n ) : List	scoring predicates calculating the Distance between them and the matching words then returning the n ones who have the least distance
trimPermutations ( List m ) : List	after getting all permutations this function is to remove permutations that may take time during the Query and return no results
