exception - Elasticsearch中的TermSuggestionBuilder Java API不返回任何结果

Question

我构建了一个TermSuggestionBuilder，如下所示

TermSuggestionBuilder termSuggest = new TermSuggestionBuilder("rule")
            .suggestMode("always") // Always, otherwise the results can vary
            // between requests.
            .text("plabel").field("_instanceName");

其中rule是索引的名称，plabel是我正在搜索的文本，_instancename是文件名。

该查询可以从Java代码正常运行，但不会返回任何结果。
构建的查询看起来像这样

"suggest" : {
"rule" : {
  "text" : "pxretrievreportdata",
  "term" : {
    "field" : "_instanceName",
    "suggest_mode" : "always"
  }
}

}

当我尝试从其余客户端[http://localhost:9200/rule/_suggest]运行相同命令时，出现以下异常

"_shards": {
"total": 1,
"successful": 0,
"failed": 1,
"failures": [
{
"index": "rule",
"shard": 0,
"reason": "BroadcastShardOperationFailedException[[rule][0] ]; nested: ElasticsearchException[failed to execute suggest]; nested: ElasticsearchIllegalArgumentException[Suggester[rule] not supported]; "
}
]
}

在其他客户端上运行时，可以给我带来预期的结果[http://localhost:9200/rule/_suggest]

{
  "my-suggestion" : {
    "text" : "plabel",
    "term" : {
      "field" : "pzInsKey"
    }
  }
}

请让我知道我在构造TermSuggestionBuilder时犯了什么错误，因为从其余客户端运行时后面的查询确实返回了预期的结果。

您在Java api中的实现无效，

我将您的代码重构为

SuggestBuilder.SuggestionBuilder suggestBuilder = new TermSuggestionBuilder("my-suggestion")
.text("plabel").field("pzInsKey").suggestMode("always");

SuggestRequestBuilder requestBuilder = client.prepareSuggest("rule")
.addSuggestion(suggestBuilder);

我没有检查输出，但应该可以。
