【问题描述】:
我一直在为两个 elasticsearch 映射参数苦苦挣扎:index 和 enabled。我正在使用 Elasticsearch 6.2.4。
这是我的情况。
映射
PUT my_index
{
"mappings": {
"_doc": {
"properties": {
"user_id": {
"type": "keyword"
},
"last_updated": {
"type": "date"
},
"session_data_index_false": {
"index" : false,
"type" : "keyword"
},
"session_data_enabled_false": {
"enabled" : false
}
}
}
}
}
索引
PUT my_index/_doc/1
{
"user_id": "jpountz",
"session_data_index_false": "hello",
"session_data_enabled_false": "hello",
"last_updated": "2015-12-06T18:22:13"
}
搜索1
GET my_index/_search
{
"query": {
"match": {
"session_data_index_false": "hello"
}
}
}
我收到以下消息的 400 错误。
{
"error": {
"root_cause": [
{
"type": "query_shard_exception",
"reason": "failed to create query: {\n \"match\" : {\n \"session_data_index_false\" : {\n \"query\" : \"hello\",\n \"operator\" : \"OR\",\n \"prefix_length\" : 0,\n \"max_expansions\" : 50,\n \"fuzzy_transpositions\" : true,\n \"lenient\" : false,\n \"zero_terms_query\" : \"NONE\",\n \"auto_generate_synonyms_phrase_query\" : true,\n \"boost\" : 1.0\n }\n }\n}",
"index_uuid": "6ByxNrjIRQmF23zcmKOvUA",
"index": "my_index"
}
],
"type": "search_phase_execution_exception",
"reason": "all shards failed",
"phase": "query",
"grouped": true,
"failed_shards": [
{
"shard": 0,
"index": "my_index",
"node": "DYPnEJWjTtm58oxZ9F-RSg",
"reason": {
"type": "query_shard_exception",
"reason": "failed to create query: {\n \"match\" : {\n \"session_data_index_false\" : {\n \"query\" : \"hello\",\n \"operator\" : \"OR\",\n \"prefix_length\" : 0,\n \"max_expansions\" : 50,\n \"fuzzy_transpositions\" : true,\n \"lenient\" : false,\n \"zero_terms_query\" : \"NONE\",\n \"auto_generate_synonyms_phrase_query\" : true,\n \"boost\" : 1.0\n }\n }\n}",
"index_uuid": "6ByxNrjIRQmF23zcmKOvUA",
"index": "my_index",
"caused_by": {
"type": "illegal_argument_exception",
"reason": "Cannot search on field [session_data_index_false] since it is not indexed."
}
}
}
]
},
"status": 400
搜索2
GET my_index/_search
{
"query": {
"match": {
"session_data_enabled_false": "hello"
}
}
}
在这种情况下,我没有收到任何错误。相反,我得到了以下结果,这意味着没有找到任何文件。
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 0,
"max_score": null,
"hits": []
}
}
检索
GET my_index/_doc/1
当然,我可以检索原始数据。
{
"_index": "my_index",
"_type": "_doc",
"_id": "1",
"_version": 1,
"found": true,
"_source": {
"user_id": "jpountz",
"session_data_index_false": "hello",
"session_data_enabled_false": "hello",
"last_updated": "2015-12-06T18:22:13"
}
}
我阅读了有关上述选项的官方文档。
另外,我读过this article,但发现它与elasticsearch 1.5 兼容。
这里有人知道这两个选项有何不同吗?
提前致谢。
最好的
【问题讨论】:
-
您是否希望
session_data_index_false上的查询不会出错而只是不返回任何文档? -
@Val 不。我只想掌握两个选项之间的区别。根据官方文档,当我想为特定字段值禁用索引时,可以使用 index 和 enabeld 选项。但不确定何时使用每个选项以及为什么一个会引发错误而一个不会?
