autocomplete 연산자

autocomplete

autocomplete 연산자는 불완전한 입력 문자열에서 문자 시퀀스를 포함하는 단어나 구문을 검색합니다. autocomplete 연산자를 사용하여 쿼리하려는 필드는 컬렉션의 인덱스 정의에 있는 자동 완성 데이터 유형으로 인덱싱되어야 합니다. 자동 완성을 위한 인덱스를 구성하는 방법을 알아보려면 자동 완성을 위한 필드 인덱싱 방법을 참조하세요.

참고

MongoDB Search might return inaccurate results for queries with more than three words in a single string.

입력 시 실시간 검색 애플리케이션에서 autocomplete 연산자를 사용하면 애플리케이션의 검색 필드에 문자가 입력될 때 단어를 더욱 정확하게 예측할 수 있습니다. autocomplete는 자동 완성을 위해 인덱스 정의에 지정된 토큰화 전략을 기반으로 한 예측 단어가 포함된 결과를 반환합니다.

If you want to build suggestions or dropdowns using the MongoDB Search autocomplete operator, we recommend that you query a collection of suggested search terms or use past search terms to populate the dropdown. If you create a separate collection of suggested search terms, you can define synonym mappings in your MongoDB Search index to search your collection for the exact or alternative words. You can track search terms and view metrics for search terms to build your collection.

autocomplete 의 구문은 다음과 같습니다:

1{
2 $search: {
3 "index": "<index name>", // optional, defaults to "default"
4 "autocomplete": {
5 "query": "<search-string>",
6 "path": "<field-to-search>",
7 "tokenOrder": "any|sequential",
8 "fuzzy": <options>,
9 "score": <options>
10 }
11 }
12}
필드
유형
설명
필요성
기본값

query

문자열 또는 문자열 배열

String or strings to search for. If there are multiple terms in a string, MongoDB Search also looks for a match for each term in the string separately.

path

문자열

검색할 인덱싱된 필드입니다. 이 필드는 autocomplete 데이터 유형으로 인덱싱되어야 합니다. 자세히 알아보려면 자동 완성을 위한 필드 인덱싱 방법을 참조하세요.

autocomplete 연산자는 path 매개 변수에서 multi 또는 wildcard (*) 옵션을 지원 하지 않습니다. 또한 path 값으로 필드 배열을 지원 하지 않습니다.

여러 필드에 걸친 autocomplete 연산자 쿼리의 예시는 여러 필드 검색을 참조하세요.

fuzzy

객체

퍼지 검색을 활성화하도록 설정합니다. 검색어 또는 용어와 유사한 문자열을 찾습니다.

no

fuzzy
.maxEdits

integer

지정된 검색 용어와 일치하는 데 필요한 최대 단일 문자 편집 수입니다. 값은 1 또는 2일 수 있습니다.

no

2

fuzzy
.prefixLength

integer

정확히 일치해야 하는 결과의 각 용어 시작 부분에 있는 문자 수입니다.

no

0

fuzzy
.maxExpansions

integer

생성하고 검색할 수 있는 최대 변형 수입니다. 이 한도는 토큰 단위로 적용됩니다.

no

50

score

객체

일치하는 검색어 결과에 할당할 점수입니다. 다음 옵션 중 하나를 사용하여 기본 점수를 수정합니다:

  • boost결과 점수에 주어진 숫자를 곱합니다.

  • constant결과 점수를 주어진 숫자로 바꿉니다.

  • function결과 점수를 주어진 표현식으로 대체합니다.

autocomplete 쿼리 실행 속도가 빨라지는 대신 점수 정확도가 떨어집니다. 자세한 학습 은 채점 동작을 참조하세요.

쿼리에서 score 사용에 대한 자세한 내용은 결과에서 문서 채점하기를 참조하십시오.

no

tokenOrder

문자열

토큰을 검색할 순서입니다. 값은 다음 중 하나일 수 있습니다:

any

쿼리의 토큰이 문서에서 어떤 순서로든 나타날 수 있음을 나타냅니다. 결과에는 토큰이 순차적으로 또는 비순차적으로 표시되는 문서가 포함됩니다. 그러나 토큰이 순차적으로 나타나는 결과는 다른 비순차적 값보다 높은 점수를 얻습니다.

sequential

쿼리의 토큰이 서로 인접해 있거나 문서의 쿼리에 지정된 순서대로 나타나야 함을 나타냅니다. 결과에는 토큰이 순차적으로 나타나는 문서만 포함됩니다.

no

any

The autocomplete operator query results that are exact matches receive a lower score than results that aren't exact matches. MongoDB Search can't determine if a query string is an exact match for an indexed text if you specify just the autocomplete-indexed token substrings. To score exact matches higher, try the following workaround:

참고

하지만, 이 우회 방법이 모든 경우에 정확히 일치하는 결과에 더 높은 점수를 보장하는 것은 아닙니다.

  1. 필드를 자동 완성문자열 유형으로 인덱싱합니다.

    MongoDB Search autocomplete boosts exact matches when an autocomplete field is also indexed as a string, thereby increasing the score of exact matches.

  2. 복합 연산자를 사용하여 쿼리합니다.

이 해결 방법의 데모는 여러 필드에 걸친 검색을 참조하세요.

다음 예시에서는 sample_mflix 데이터베이스의 movies 컬렉션을 사용합니다. 클러스터에 샘플 데이터 세트를 로드한 경우 자동 완성을 위한 정적 인덱스를 생성하고 클러스터에서 예시 쿼리를 실행할 수 있습니다.

다음 탭에는 edgeGram, rightEdgeGram, nGram 토큰화 전략에 대한 샘플 인덱스 정의가 포함되어 있습니다. 자동 완성 유형 외에도 샘플 인덱스 정의에는 title 필드에 문자열토큰 유형이 포함되어 있습니다.

다음 쿼리는 title 필드에 pre 문자가 포함된 영화를 검색합니다. 쿼리는 다음을 사용합니다.

필드

설명

maxEdits

쿼리를 문서의 단어와 일치시키기 위해 쿼리 문자열 pre에 하나의 문자 변형만 허용됨을 나타냅니다.

prefixLength

쿼리를 문서의 단어와 일치시킬 때 쿼리 문자열 pre 의 첫 번째 문자가 변경될 수 없음을 나타냅니다.

maxExpansions

쿼리 문자열을 문서의 단어와 일치시킬 때 pre에 대해 최대 256개의 유사한 용어를 고려할 수 있음을 나타냅니다.

다음 코드 예제에서는:

  • pymongo, MongoDB의 Python 드라이버 및 dns 모듈을 가져옵니다. 이 모듈은 DNS 시드 리스트 연결 문자열을 사용하여 pymongoAtlas에 연결하는 데 필요합니다.

  • MongoClient 클래스의 인스턴스를 만들어 Atlas 클러스터에 대한 연결을 설정합니다.

  • 다음을 사용하는 쿼리를 실행합니다.

    • $search 단계에서 텀 검색

    • $limit 단계를 사용하여 출력을 5개의 결과로 제한합니다.

다음 쿼리는 title 필드에 men with 문자가 포함된 영화를 검색합니다. 이 쿼리는 또한 tokenOrder 필드를 사용하여 쿼리가 토큰을 any 순서로 검색할지 또는 sequential 순서로 검색할지를 지정합니다.

키워드 분석기로 필드를 인덱싱하여 title 필드에서 단어나 문구로 시작하는 영화 제목을 검색할 수 있습니다.

You must index the field using the keyword analyzer with the edgeGram tokenization strategy to retrieve results for the following sample query. If you index the field using any other built-in analyzers, MongoDB Search doesn't return any results because it doesn't index your text field as a single term. The edgeGram tokenization strategy creates tokens starting at the left side of the words.

You must also set foldDiacritics to true to return case-agnostic results. If you set foldDiacritics to false, the letter case of the query term must exactly match the letter case in the document for MongoDB Search to return any results.

{
"mappings": {
"dynamic": false,
"fields": {
"title": [

"type": "token"

}
}

다음 쿼리는 Fast & 단어로 시작하는 영화 제목을 검색합니다.

다음 쿼리를 복사하여 Query Editor에 붙여 넣은 다음 Query Editor에서 Search 버튼을 클릭합니다.

[
{
$search: {
autocomplete: {
path: "title",
query: "Fast &",
tokenOrder: "sequential"

각 쿼리에는

  • $limit 단계를 설정하여 출력을 4개의 결과로 제한합니다.

  • title을 제외한 모든 필드를 제외하는 $project 단계

db.movies.aggregate([
