我正在尝试做一个简单的gas-filter查询：

{
   "query": {
      "match_all" : {}
   },

       "gas-filter": {
       "name": "SearchResultCypherfilter",
       "query": "MATCH (m:Movie)-[ACTED_IN*1..3]-(p) WHERE m.title =~'.*The Devil.*' RETURN p.uuid as id"
   }
}

但它不起作用。我收到此错误消息：

{
  "error": {
    "root_cause": [
      {
        "type": "search_parse_exception",
        "reason": "failed to parse search source. unknown search element [gas-filter]",
        "line": 4,
        "col": 7
      }
    ],
    "type": "search_phase_execution_exception",
    "reason": "all shards failed",
    "phase": "query",
    "grouped": true,
    "failed_shards": [
      {
        "shard": 0,
        "index": "1abp502-01-index",
        "node": "KcFzGx6hQDKnfbvB8ZTtuQ",
        "reason": {
          "type": "search_parse_exception",
          "reason": "failed to parse search source. unknown search element [gas-filter]",
          "line": 4,
          "col": 7
        }
      }
    ]
  },
  "status": 400
}

这很奇怪，因为我已经在远程计算机上进行了配置Elasticsearch，Neo4j就像在我的个人计算机上一样。它正在我的电脑上运行。唯一的区别是远方有代理。但我认为这不是问题，因为如果是我应该收到另一条错误消息，可能类似于connection refused.

我发现的唯一相关和相似的主题是这个。它说这个错误可能是因为另一个elasticsearch在后台运行的实例。所以我尝试了建议的解决方案。因为我在 Windows 上工作，所以等效的命令ps aux | grep elasticsearch是TASKLIST /M elasticsearch，但这并没有给我任何东西。当我只做tasklist /v或即使在运行它时tasklist /svc也无法在进程列表中找到它时。elasticsearch

有什么想法吗？谢谢！

我遵循了图形辅助搜索的文档，但仍然无法正常工作。我卸载graph-aided-search并再次安装它，如下所示：

Installed graph-aided-search into C:\Users\User\Documents\elasticsearch-2.3.2\plugins\graph-aided-search

但仍然得到相同的错误failed to parse search source. unknown search element [gas-filter]。此消息说GAS未安装在ES 2.3.2. 但是，graph-aided search已正确安装，所以不GAS应该自动安装graph-aided-search?

会不会跟Neo4j版本有关系？我正在与neo4j-community-3.1.4
