spring-boot-starter-data-elasticsearch 导致未知设置分析器/search_anal



>上下文：我想使用 Spring-Data 连接到 ElasticSearch 并检索在单词的任何位置搜索至少两个字母的数据。

例子：

已加载以下两个文档：

[
{
"conta": "1234",
"sobrenome": "Carvalho",
"nome": "Demetrio"
},
{
"conta": "5678",
"sobrenome": "Carv",
"nome": "Deme"
}   
]
通过"de"或"me">

rio"进行搜索将带来所有两个，而搜索"demet"只会带来第一个。

我可以通过在 7.6.2 版中创建此索引来成功做到这一点。(放/考伦蒂斯塔斯(

{
"settings": {
"index.max_ngram_diff": 10,
"analysis": {
"filter": {
"autocomplete_filter": {
"type": "ngram",
"min_gram": 2,
"max_gram": 8
}
},
"analyzer": {
"autocomplete": {
"type": "custom",
"tokenizer": "standard",
"filter": [
"lowercase",
"autocomplete_filter"
]
}
}
}
},
"mappings": {
"properties": {
"conta": {
"type": "text"
},
"sobrenome": {
"type": "text"
},
"nome": {
"type": "text",
"analyzer": "autocomplete",
"search_analyzer": "standard"
}
}
}
}

并使用 GET correntistas/_doc/_search 从邮递员成功搜索

{
"query" :{
"match" :{
"nome" :"De"
}
}
}

因此，自己的Elasticsearch完全没有问题。

但是，问题是读取从 Spring 数据搜索或创建索引。好吧，从 Spring 创建索引不是我们将在生产中使用的东西，但对于开发人员来说是值得的。尽管如此，就我而言，从 Spring 开始在 ElastiSearch 中进行搜索是必须的。

我知道 Elastic 6 和 7 之间存在一些不兼容，并且据我所知，Spring-data 仍然没有 7 依赖关系。顺便说一句，我不能将 ElasticSearch 从 7 降级到 6，我确实使用 Spring 编写了一个微服务，以便从单词中的任何位置搜索用户类型。我相信这是一个主要由Spring-data-elasticsearch支持者回答的问题或问题，但也许还有另一种选择可以来自Elasticsearch用户。请不要建议我既不使用 * 也不使用正则表达式作为替代方案，除非您是 100% 它将利用 ElasticSearch 引擎(我很确定在 Elastic 上搜索期间使用 * 是一种糟糕的性能实践(

设置文件存储在哪里？

@Setting(settingPath = "data/es-config/elastic-setting.json")

意味着数据目录与实体类处于同一级别。 如果你在src/main/resources/data/es-config中有它，请更改值：

@Setting(settingPath = "/data/es-config/elastic-setting.json")

编辑：要将Spring Data Elasticsearch与Elasticsearch7一起使用，您需要Spring Data Elasticsearch 4.0,5月12日发布
