使用映射和设置创建索引时未发现分析器异常

嗨,我正在使用Elastic Search

elasticsearch-0.90.2版本。我正在尝试使用jsonBuilder使用自定义分析器来映射分析器,同时创建索引时,它会抛出未找到分析器的异常。

设置 :-

       XContentBuilder settings = XContentFactory.jsonBuilder()

.startObject()

.startObject("settings")

.startObject("analysis")

.startObject("analyzer")

.startObject("search_analyzer")

.field("tokenizer", "ngram_specification")

.field("type", "custom")

.field("filter", new String[]{ "ngram_specification"})

.endObject()

.endObject()

.startObject("ngram_specification")

.field("type", "nGram")

.field("min_gram", "2")

.field("max_gram", "5")

.endObject()

.endObject()

.endObject()

.endObject();

映射:-

  XContentBuilder mapping = XContentFactory.jsonBuilder()

.startObject()

.startObject("sample")

.startObject("properties")

.startObject("email").field("type", "string").field("index", "analyzed").field("analyzer", "search_analyzer")

.endObject()

.endObject()

.endObject()

.endObject();

像这样创建索引:

        CreateIndexRequest indexRequest = new CreateIndexRequest(indexName);

indexRequest.settings(settings);

indexRequest.mapping("sample", mapping);

CreateIndexResponse response = client.admin().indices().create(indexRequest).actionGet();

例外情况:

任何人都可以告诉这种方法中的错误吗?

回答:

我找到了解决方案。在“设置”中,如果您使用“索引”而不是“设置”,那么它将正常工作。

这是错误的:

XContentBuilder settings = XContentFactory.jsonBuilder()

.startObject()

.startObject("settings") // "settings"

.startObject("analysis")

但是这样

XContentBuilder settings = XContentFactory.jsonBuilder()

.startObject()

.startObject("index") // "index" instead of "settings"

.startObject("analysis")
