Atlas 클러스터의 데이터에 대해 시맨틱 검색을 수행하는 방법

이 페이지의 내용

  • 전제 조건
  • Atlas Vector Search 인덱스 만들기
  • 필요한 액세스 권한
  • 절차
  • $vectorSearch 집계 파이프라인 단계를 사용하여 쿼리 실행
  • 개요
  • 절차

이 튜토리얼에서는 Atlas 클러스터의 sample_mflix.embedded_movies 컬렉션에 있는 plot_embedding 필드에 있는 벡터에 대해 ANN 검색을 수행하는 방법을 설명합니다. 다음 단계를 통해 이를 시연합니다.

  1. sample_mflix.embedded_movies 컬렉션의 plot_embedding라는 숫자 필드에 Atlas Vector Search 인덱스를 생성합니다.

  2. sample_mflix.embedded_movies 컬렉션의 plot_embedding 필드에 Atlas Vector Search 쿼리를 실행합니다.

이 튜토리얼을 완료하려면 다음 조건을 충족해야 합니다.

  • Atlas cluster에 설치된 MongoDB 버전 6.0.11 또는 v7.0.2 이상( RC 포함).

  • Atlas 클러스터에 로드된 샘플 데이터

    참고

    Atlas에서 벡터를 효율적으로 저장하고 수집하기 위해 샘플 데이터의 임베딩을 BSON 벡터로 변환합니다. 자세한 내용은 네이티브 임베딩을 BSON 벡터로 변환하는 방법을 참조하세요.

  • 다음 클라이언트 중 하나를 사용하여 Atlas cluster 에서 쿼리를 실행 합니다.

    • mongosh

    • A MongoDB Java 드라이버

    • MongoDB Go 드라이버

    • MongoDB 노드 드라이버

    • PyMongo

    참고

    "" 집계 단계를 통해 MongoDB 드라이버 를 사용하여 "" 쿼리를 실행 수 있습니다. ""에는 앞의 목록에 있는 드라이버에 대한 예제만 포함되어 있습니다.

    Atlas CLI를 사용하여 만든 로컬 Atlas 배포와 함께 Atlas Vector Search를 사용할 수도 있습니다. 자세한 내용은 로컬 Atlas 배포 만들기를 참조하세요.

다음 쿼리는 $vectorSearch 파이프라인 단계를 사용하여 지정된 벡터 임베딩과 일치하는 영화를 검색합니다. 이 쿼리에서는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 쿼리는 최대 100개의 최근접 이웃에 대한 검색을 지정하고 결과를 10개의 문서로만 제한합니다. 또한 다음 작업을 수행하기 위해 $project 단계를 지정합니다.

  • _id 필드를 제외하고 title, genres, plot, year 필드만 결과에 포함합니다.

  • 결과의 각 문서에 대한 벡터 검색 점수를 보여주는 score 필드를 추가합니다.

    다음 쿼리는 벡터 임베딩을 사용하여 문자열 무술에 대한 plot_embedding 필드를 검색합니다. 이 쿼리는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 집계 파이프라인 연산자와 비교 쿼리 연산자를 지정하여 데이터를 필터링하기 위해 연산자를 함께 사용하는 방법을 보여줍니다.

    필터는 $or 집계 파이프라인 연산자를 사용하여 다음 기준 중 하나와 일치하는 영화 문서를 찾습니다.

    • genres 필드로 필터링하여 crime 장르에 속하지 않는 영화를 찾습니다.

    • year 필드로 필터링하여 2015년 또는 그 이전에 개봉된 영화를 찾고 그리고 genres 필드로 필터링하여 action 장르의 영화를 찾습니다.

다음 쿼리는 $vectorSearch 파이프라인 단계를 사용하여 지정된 벡터 임베딩과 일치하는 영화를 검색합니다. 이 쿼리에서는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 쿼리는 최대 100개의 최근접 이웃에 대한 검색을 지정하고 결과를 10개의 문서로만 제한합니다. 또한 다음 작업을 수행하기 위해 $project 단계를 지정합니다.

  • _id 필드를 제외하고 title, genres, plot, year 필드만 결과에 포함합니다.

  • 결과의 각 문서에 대한 벡터 검색 점수를 보여주는 score 필드를 추가합니다.

다음 쿼리는 문자열 historical heist에 대한 벡터 임베딩을 사용하여 plot_embedding 필드를 검색합니다. 이 쿼리는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 시맨틱 검색을 수행할 문서를 사전 필터링하기 위해 필드당 여러 비교 쿼리 연산자를 지정합니다.

이 필터는 $and 집계 파이프라인 연산자를 사용하여 다음 기준과 모두 일치하는 동영상 문서를 찾습니다.

  • genres 필드를 사용하여 drama, western, crime가 아닌 action, adventure, family에 속하는 영화를 필터링하세요.

  • year 필드로 필터링하여 1960년부터 2000년까지 개봉한 영화를 찾습니다.

다음 쿼리는 벡터 임베딩을 사용하여 문자열 무술에 대한 plot_embedding 필드를 검색합니다. 이 쿼리는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 집계 파이프라인 연산자와 비교 쿼리 연산자를 지정하여 데이터를 필터링하기 위해 연산자를 함께 사용하는 방법을 보여줍니다.

필터는 $or 집계 파이프라인 연산자를 사용하여 다음 기준 중 하나와 일치하는 영화 문서를 찾습니다.

  • genres 필드로 필터링하여 crime 장르에 속하지 않는 영화를 찾습니다.

  • year 필드로 필터링하여 2015년 또는 그 이전에 개봉된 영화를 찾고 그리고 genres 필드로 필터링하여 action 장르의 영화를 찾습니다.

다음 쿼리는 $vectorSearch 파이프라인 단계를 사용하여 지정된 벡터 임베딩과 일치하는 영화를 검색합니다. 이 쿼리에서는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 쿼리는 최대 100개의 최근접 이웃에 대한 검색을 지정하고 결과를 10개의 문서로만 제한합니다. 또한 다음 작업을 수행하기 위해 $project 단계를 지정합니다.

  • _id 필드를 제외하고 title, genres, plot, year 필드만 결과에 포함합니다.

  • 결과의 각 문서에 대한 벡터 검색 점수를 보여주는 score 필드를 추가합니다.

다음 쿼리는 문자열 historical heist에 대한 벡터 임베딩을 사용하여 plot_embedding 필드를 검색합니다. 이 쿼리는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 시맨틱 검색을 수행할 문서를 사전 필터링하기 위해 필드당 여러 비교 쿼리 연산자를 지정합니다.

이 필터는 $and 집계 파이프라인 연산자를 사용하여 다음 기준과 모두 일치하는 동영상 문서를 찾습니다.

  • genres 필드를 사용하여 drama, western, crime가 아닌 action, adventure, family에 속하는 영화를 필터링하세요.

  • year 필드로 필터링하여 1960년부터 2000년까지 개봉한 영화를 찾습니다.

다음 쿼리는 벡터 임베딩을 사용하여 문자열 무술에 대한 plot_embedding 필드를 검색합니다. 이 쿼리는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 집계 파이프라인 연산자와 비교 쿼리 연산자를 지정하여 데이터를 필터링하기 위해 연산자를 함께 사용하는 방법을 보여줍니다.

필터는 $or 집계 파이프라인 연산자를 사용하여 다음 기준 중 하나와 일치하는 영화 문서를 찾습니다.

  • genres 필드로 필터링하여 crime 장르에 속하지 않는 영화를 찾습니다.

  • year 필드로 필터링하여 2015년 또는 그 이전에 개봉된 영화를 찾고 그리고 genres 필드로 필터링하여 action 장르의 영화를 찾습니다.

다음 쿼리는 $vectorSearch 파이프라인 단계를 사용하여 지정된 벡터 임베딩과 일치하는 영화를 검색합니다. 이 쿼리에서는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 쿼리는 최대 100개의 최근접 이웃에 대한 검색을 지정하고 결과를 10개의 문서로만 제한합니다. 또한 다음 작업을 수행하기 위해 $project 단계를 지정합니다.

  • _id 필드를 제외하고 title, genres, plot, year 필드만 결과에 포함합니다.

  • 결과의 각 문서에 대한 벡터 검색 점수를 보여주는 score 필드를 추가합니다.

다음 쿼리는 문자열 historical heist에 대한 벡터 임베딩을 사용하여 plot_embedding 필드를 검색합니다. 이 쿼리는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 시맨틱 검색을 수행할 문서를 사전 필터링하기 위해 필드당 여러 비교 쿼리 연산자를 지정합니다.

이 필터는 $and 집계 파이프라인 연산자를 사용하여 다음 기준과 모두 일치하는 동영상 문서를 찾습니다.

  • genres 필드를 사용하여 drama, western, crime가 아닌 action, adventure, family에 속하는 영화를 필터링하세요.

  • year 필드로 필터링하여 1960년부터 2000년까지 개봉한 영화를 찾습니다.

다음 쿼리는 벡터 임베딩을 사용하여 문자열 무술에 대한 plot_embedding 필드를 검색합니다. 이 쿼리는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 집계 파이프라인 연산자와 비교 쿼리 연산자를 지정하여 데이터를 필터링하기 위해 연산자를 함께 사용하는 방법을 보여줍니다.

필터는 $or 집계 파이프라인 연산자를 사용하여 다음 기준 중 하나와 일치하는 영화 문서를 찾습니다.

  • genres 필드로 필터링하여 crime 장르에 속하지 않는 영화를 찾습니다.

  • year 필드로 필터링하여 2015년 또는 그 이전에 개봉된 영화를 찾고 그리고 genres 필드로 필터링하여 action 장르의 영화를 찾습니다.

다음 쿼리는 $vectorSearch 파이프라인 단계를 사용하여 지정된 벡터 임베딩과 일치하는 영화를 검색합니다. 이 쿼리에서는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 쿼리는 최대 100개의 최근접 이웃에 대한 검색을 지정하고 결과를 10개의 문서로만 제한합니다. 또한 다음 작업을 수행하기 위해 $project 단계를 지정합니다.

  • _id 필드를 제외하고 title, genres, plot, year 필드만 결과에 포함합니다.

  • 결과의 각 문서에 대한 벡터 검색 점수를 보여주는 score 필드를 추가합니다.

다음 쿼리는 문자열 historical heist에 대한 벡터 임베딩을 사용하여 plot_embedding 필드를 검색합니다. 이 쿼리는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 시맨틱 검색을 수행할 문서를 사전 필터링하기 위해 필드당 여러 비교 쿼리 연산자를 지정합니다.

이 필터는 $and 집계 파이프라인 연산자를 사용하여 다음 기준과 모두 일치하는 동영상 문서를 찾습니다.

  • genres 필드를 사용하여 drama, western, crime가 아닌 action, adventure, family에 속하는 영화를 필터링하세요.

  • year 필드로 필터링하여 1960년부터 2000년까지 개봉한 영화를 찾습니다.

다음 쿼리는 벡터 임베딩을 사용하여 문자열 무술에 대한 plot_embedding 필드를 검색합니다. 이 쿼리는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 집계 파이프라인 연산자와 비교 쿼리 연산자를 지정하여 데이터를 필터링하기 위해 연산자를 함께 사용하는 방법을 보여줍니다.

필터는 $or 집계 파이프라인 연산자를 사용하여 다음 기준 중 하나와 일치하는 영화 문서를 찾습니다.

  • genres 필드로 필터링하여 crime 장르에 속하지 않는 영화를 찾습니다.

  • year 필드로 필터링하여 2015년 또는 그 이전에 개봉된 영화를 찾고 그리고 genres 필드로 필터링하여 action 장르의 영화를 찾습니다.

다음 쿼리는 $vectorSearch 파이프라인 단계를 사용하여 지정된 벡터 임베딩과 일치하는 영화를 검색합니다. 이 쿼리에서는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 쿼리는 최대 100개의 최근접 이웃에 대한 검색을 지정하고 결과를 10개의 문서로만 제한합니다. 또한 다음 작업을 수행하기 위해 $project 단계를 지정합니다.

  • _id 필드를 제외하고 title, genres, plot, year 필드만 결과에 포함합니다.

  • 결과의 각 문서에 대한 벡터 검색 점수를 보여주는 score 필드를 추가합니다.

다음 쿼리는 문자열 historical heist에 대한 벡터 임베딩을 사용하여 plot_embedding 필드를 검색합니다. 이 쿼리는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 시맨틱 검색을 수행할 문서를 사전 필터링하기 위해 필드당 여러 비교 쿼리 연산자를 지정합니다.

이 필터는 $and 집계 파이프라인 연산자를 사용하여 다음 기준과 모두 일치하는 동영상 문서를 찾습니다.

  • genres 필드를 사용하여 drama, western, crime가 아닌 action, adventure, family에 속하는 영화를 필터링하세요.

  • year 필드로 필터링하여 1960년부터 2000년까지 개봉한 영화를 찾습니다.

다음 쿼리는 벡터 임베딩을 사용하여 문자열 무술에 대한 plot_embedding 필드를 검색합니다. 이 쿼리는 plot_embedding 필드의 벡터 임베딩과 동일한 ada-002-text 임베딩을 사용합니다. 집계 파이프라인 연산자와 비교 쿼리 연산자를 지정하여 데이터를 필터링하기 위해 연산자를 함께 사용하는 방법을 보여줍니다.

필터는 $or 집계 파이프라인 연산자를 사용하여 다음 기준 중 하나와 일치하는 영화 문서를 찾습니다.

  • genres 필드로 필터링하여 crime 장르에 속하지 않는 영화를 찾습니다.

  • year 필드로 필터링하여 2015년 또는 그 이전에 개봉된 영화를 찾고 그리고 genres 필드로 필터링하여 action 장르의 영화를 찾습니다.
