[英]ElasticSearch Facets Terms Query float precision
I have some problems with the facets terms query (with ElasticSearch 1.7.0), all float values are right stored in the database and in the elasticsearch bulk too, but when I request the data I get the values like that "2.99000000954". 我在facets字词查询(使用ElasticSearch 1.7.0)时遇到一些问题,所有浮点值也都正确存储在数据库中,并且也大量存储在Elasticsearch中,但是当我请求数据时,我得到的值类似于“ 2.99000000954”。
The strange thing is that when I put my request with "2.99000000954", the engine found the good Article related with this data, the article with the "2.99" value. 奇怪的是,当我用“ 2.99000000954”发出请求时,引擎找到了与此数据相关的好文章,即具有“ 2.99”值的文章。
Please have a look on the below codes files and the curl call request: 请查看以下代码文件和curl调用请求:

我找到了解决方案,将数据类型从float更改为long,一切正常!
