使用Java API定义自定义ElasticSearch Analyzer [英] Define custom ElasticSearch Analyzer using Java API

问题描述

有没有办法创建索引并使用Java API指定自定义分析器？它支持在索引创建时添加映射，但是我无法找到一种方法来执行类似的操作，而不需要通过HTTP PUT发送JSON：

Is there a way to create an index and specify a custom analyzer using the Java API? It supports adding mappings at index creation, but I can't find a way to do something like this without sending the JSON via HTTP PUT:

curl -XPUT localhost:9200/twitter?pretty=true -d '{
"analysis": {
       "analyzer": {
            "steak" : {
                "type" : "custom", 
                "tokenizer" : "standard",
                "filter" : ["snowball", "standard", "lowercase"]
            }
        }
    }
}'

我可以使用JSONBuilder构建这样一个查询，但是我在API中找不到任何地方可以运行它， CreateIndexRequest 没有任何可以使用的东西，而且$ code> client.admin （）.indices（），尽可能看到。

I can build such a query using JSONBuilder, but I can't find no place in the API where to run it, CreateIndexRequest doesn't have anything I can use and neither does client.admin().indices(), as far as I can see. What's the right way to do this?

推荐答案

您可以使用 client.admin（）设置分析器。指数（）。prepareCreate（ 推）。setSettings（...）。有几种方法来构建设置。您可以从文本，地图或甚至使用jsonBuilder加载它们，如果这是您想要的：

You can set analyzer using client.admin().indices().prepareCreate("twitter").setSettings(...). There are several ways to build settings. You can load them from text, map or even use jsonBuilder if that's what you want:

client.admin().indices().prepareCreate("twitter")
            .setSettings(Settings.settingsBuilder().loadFromSource(jsonBuilder()
                .startObject()
                    .startObject("analysis")
                        .startObject("analyzer")
                            .startObject("steak")
                                .field("type", "custom")
                                .field("tokenizer", "standard")
                                .field("filter", new String[]{"snowball", "standard", "lowercase"})
                            .endObject()
                        .endObject()
                    .endObject()
                .endObject().string()))
            .execute().actionGet();
