Examples with Query org.springframework.data.elasticsearch.core.query.Query used on opensource projects

Example 26 with Query

use of org.springframework.data.elasticsearch.core.query.Query in project spring-study by backtony.

the class MemberSearchQueryRepository method findByMatchesDescription.

/**
 * 일반적으로 원하는 description이 매칭되는 것들에 맞게 score 계산해서 찾아준다.
 */
public List<MemberDocument> findByMatchesDescription(String description, Pageable pageable) {
    Criteria criteria = Criteria.where("description").matches(description);
    Query query = new CriteriaQuery(criteria).setPageable(pageable);
    SearchHits<MemberDocument> search = operations.search(query, MemberDocument.class);
    return search.stream().map(SearchHit::getContent).collect(Collectors.toList());
}

Example 27 with Query

use of org.springframework.data.elasticsearch.core.query.Query in project spring-study by backtony.

the class MemberSearchQueryRepository method findByContainsDescription.

/**
 * 형태소 분석기 nori를 사용할 경우 주의해야한다.
 * MemberDocument의 description이 text타입이기 때문에 노리 분석기가 토큰화 시키는데
 * member.json 파일에 보면 안녕하세요 ~~ 이런식으로 되어있는데 토큰화 될 때 안녕, 하, 시, 어요 이렇게 토큰화된다.
 * 따라서 요청 description에 "안녕하세요"로 들어올 경우 쿼리가 *안녕하세요*로 나가기 때문에 찾을 수 없게 된다.
 * 따라서 Contains를 사용할 경우 노리 분석기가 어떻게 동작하는지 잘 인지하고 사용해야 한다.
 *  contains는 앞쪽에 *가 붙어서 쿼리 성능을 급격히 저하시키기 때문에 웬만하면 사용하지 않는 것이 좋다.
 *
 *  nori 형태소가 어떻게 토큰화 하여 저장하는지는 키바나 콘솔에서 아래와 같이 검색하보면 어떤 식으로 토큰화 되는지 확인 가능
 *  {
 *   "tokenizer": "nori_tokenizer",
 *   "text": "원하는 내용"
 * }

Example 28 with Query

use of org.springframework.data.elasticsearch.core.query.Query in project spring-native by spring-projects-experimental.

the class ConferenceCustomRepositoryImpl method findBySomeCustomImplementation.

@Override
