Elasticsearch多个分析仪无法正常工作

Question

我有一个小测试注册，标题如下： ' Santos（SAN）XAvaíFC（AVAI） - Canindé（圣保罗-SP）'

如果我尝试搜索任何字词，例如“ san ”或“ avai ”或“avaí”或“ santos < / strong>'它工作正常。但是如果我尝试搜索“ Santos（SAN）XAvaíFC（AVAI）”，它应该只返回1个reg并返回所有3个reg。

以下是测试数据： https://gist.github.com/PtkFerraro/83c4b693cf770c3320fe0530a4e1ddc7

您似乎希望支持两种不同类型的搜索：（1）您将单个字词（如san或avai与足球比赛标题匹配）和（2）精确词组匹配部分或全部比赛名称。

您正在使用的query string query被解析为单独的术语，因此在您的示例Santos (SAN) X Avaí FC (AVAI)中包含与所有3个示例文档匹配的X令牌，因为它们各自包含X

您的查询：

{
    "query_string": {
        "query": "Santos (SAN) X Avaí FC (AVAI)",
        "fields": [
            "title^10",
            "match_title.snowball^2",
            "match_title.shingles^2",
            "match_title.ngrams"
        ]
    }
}

如果您想匹配整个短语，则需要使用可执行此操作的查询。评论中提出了Match phrase queries。您还可以使用匹配查询，operator设置为and查询中的字词。这样您就可以使用相同的查询类型将avai与Santos (SAN) X Avaí FC (AVAI)匹配。

我认为你可能对这样的事情感到高兴：

{
  "query": {
    "multi_match" : {
      "query":      "Santos (SAN) X Avaí FC (AVAI)",
      "fields":     [
            "title^10",
            "match_title.snowball^2",
            "match_title.shingles^2",
            "match_title.ngrams"
        ],
        "operator":   "and" 
    }
  }
}
