使用 Elastic4s 创建索引设置

Question

我有一些类：

class SomeClass(val client: ElasticClient, val config: Config, val configName: String)(implicit val ec: ExecutionContext)
extends ElasticSearchRepositoryWrapper[AnotherClass]{
override def mapping: Option[MappingDefinition] = Some(
properties(
KeywordField("id"),
TextField("name").fielddata(true).analyzer("ngram_analyzer"),
KeywordField("lang"),
BasicField("order", "long"),
...
)
)

我正在使用此映射创建具有repository.createIndexIfNotExists()的索引。
现在，我必须在索引设置中创建ngram_analyzer：

"settings": {
"index": {
"analysis": {
"analyzer": {
"ngram_analyzer": {
"filter": [
"lowercase"
],
"tokenizer": "my_tokenizer"
}
},
"tokenizer": {
"my_tokenizer": {
"token_chars": [
"letter",
"digit"
],
"min_gram": "3",
"type": "ngram",
"max_gram": "3"
}
}
}
}

如何使用 elastic4s 做到这一点？

Answer 1

好的。createIndexIfNotExists()的许多功能已被弃用。因此，我使用了放置分析仪的CreateIndexRequest：

CreateIndexRequest(repository.indexName, analysis = Option(ngramAnalyzer), mapping = repository.mapping)
.shards(repository.shards)
.replicas(repository.replicas)

我像这样初始化我的分析器：

val ngramAnalyzer = Analysis(
List(CustomAnalyzer(
name = "ngram_analyzer",
tokenizer = "ngram",
charFilters = Nil,
tokenFilters = List("lowercase")
))
)
