如何使用Elasticsearch在数组中搜索字段

Question

I am using the index array field json as,

"productdetailsarray":
{
"properties":{
"producttone" : { "type" : "integer", "store" : "yes", "precision_step" : "8" },
"productsaleid" : { "type" : "integer", "store" : "yes", "precision_step" : "8" },
"productcoverage" : { "type" : "integer", "store" : "yes", "precision_step" : "8" },
"productdataid" : { "type" : "integer", "store" : "yes", "precision_step" : "8" },
"productid" : { "type" : "integer", "store" : "yes", "precision_step" : "8" }}
}

How to search the data inside the array?

Answer 1

Simple parse the JSon using a library like GSon:

MyClassToModelTheData data = new Gson().fromJson(theJsonString, MyClassToModelTheData.class);

Once in object-form, you can use any of the standard Java constructs to search the data.

If you use Maven, you can use the following to import GSon:

<!-- For parsing JSon -->
<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>1.7.1</version>
</dependency>
