# LeaderFollower Filter
- A filter for extracting atomic keyword from queried sentence
*Conception*
> This filter excludes the word token which is enclosing some other keyword.
> Therefore, a word list that has been applied this filter will consist of atomic keyword(Lowest Range).
> By this filter, the efficiency of search engine will be increased since the amount of words to search is small.
*Usage*
```java
import java.util.HashMap;
import java.util.Map;
public class AppMain {
public static void main(String[] args){
String s = "";
WordSet wordSet = new WordSet();
wordSet.addWord(new Word("대한민국", "대한민국", 0));
wordSet.addWord(new Word("서울", "서울", 0));
wordSet.addWord(new Word("학동", "학동", 0));
wordSet.addWord(new Word("과일", "과일", 0));
wordSet.addWord(new Word("배", "배", 0));
wordSet.addWord(new Word("사과", "사과", 0));
Map map = new HashMap<>();
map.put("학동,배", 0);
map.put("과일,사과", 0);
map.put("과일,배", 0);
map.put("대한민국,서울", 0);
map.put("대한민국,학동", 0);
map.put("서울,학동", 0);
s = "";
for(Word w : wordSet.getWords()) s += w.getNorWord() + " ";
System.out.println("검색키워드 [" + s.trim() + "]");
s = "";
for(Word ws : LFFilter.execute(wordSet, map).getWords()) s += ws.getNorWord() + " ";
System.out.println("추출키워드 [" + s.trim() + "]");
}
}
```
*Output*
```sh
검색키워드 [대한민국 서울 학동 과일 배 사과]
추출키워드 [배 사과]
Process finished with exit code 0
```
