我创建根据elasticsearch文档名为 “synonym_filter”Elasticsearch同义词返回0结果
"synonym_filter": {
"type": "synonym",
"synonyms": [
"adidas, xyz, abc",
"nike, rofl, lol"
]
}
并命名为分析仪 “的同义词”
"synonyms": {
"filter": [
"lowercase",
"synonym_filter"
],
"tokenizer": "standard"
},
的同义词滤波器。现在完整的设置是这样的。

测试分析仪
GET /test6_de_idx1/_analyze
{
"analyzer" : "synonyms",
"text" : "xyz is the English queen"
}
显示，分析仪正在工作：

"start_offset": 0,
"end_offset": 3,
"type": "<ALPHANUM>",
"position": 0
},

但是当我做一个测试搜索用同义词，我得到0结果与阿迪达斯，这是在数据中使用我得到的结果。
GET /test6_de_idx1/_search?q=xyz&size=5

},
"hits": {

请问是什么问题？

EDIT3 “同义词”分析器映射属性字段但它仍然不起作用。我做对了吗？

感谢您的快速回复，我编辑了这个问题，以表明它不适合您的提示。也许击中的结果显示更多细节。 –
也提供该索引的映射。 –
我做了第二次编辑显示映射。现在我明白“_all”是什么意思了，但我不明白应该如何使用同义词分析器。 –
