Class MatchType

public class MatchType
extends Object

Provides a typesafe enum pattern for the match type. The match type requested may be a complete match, an undermatch, or a partial undermatch.

• A Complete Match is the first and most exact method of matching the text search (pattern) string. Through Complete Match, a match occurs and a concept is retrieved when the concept term (target string) contains the same words as the specified pattern string, in any order. Every concept term (target string) in the knowledgebase that contains all the words in the pattern string (in any order) is retrieved.

• The second matching option is called Under Match. When Under Match is selected, Complete Match is attempted first; if no matches occur, Under Match is attempted. Through Under Match, a match occurs if the target string matches the pattern string words (in any order) and the target string also contains words in addition to those in the pattern string.

• The third matching option is called Partial Under Match. If Partial Under Match is selected, and no matches occur from the Complete Match, Under Match is attempted. If no matches occur from Under Match, Partial Under Match match is attempted. Through Partial Under Match, a match occurs if the target string contains all remaining words (in any order) after certain words in the pattern string have been discarded as part of 2 cycles.

  • In the initial discard cycle, pattern string words that are neither verbs nor nouns are discarded.
  • If a match does not occur, a second cycle occurs in which words are discarded from the pattern string until only pure words remain (a pure word is one that is a noun and/or verb, and cannot be interpreted as anything else (e.g., as an adjective).
  • For example, the word Moderate in the search pattern Moderate Attack can be a verb, a noun, or an adjective, and would be discarded for a Partial Under Match. Only words that are pure verbs and/or nouns are retained in the pattern string; if all pure words in the pattern string match a target string, a match is returned.
