Hi,

I am working on Recommendation engine where trying to retrieve the purchase data, I need to sort the data based on most occurrence means in order index productId is one of the field.  
For ex :  
o111, prod111,  
o222, prod222,  
o333, prod111,  
o444, prod333,  
o555, prod222,  
o666, prod111

I want to get the data as below  
o111, prod111,  
o333, prod111,  
o666, prod111,  
o222, prod222,  
o555, prod222,  
o444, prod333,

I am using Java high level rest client, Please suggest me the elastic search query and java example if possible.

ThanksInAdvance.

You should be able to just use the query sorting capability to sord by `productId` ASC: [https://www.elastic.co/guide/en/elasticsearch/reference/7.x/search-request-body.html#request-body-search-sort](https://www.elastic.co/guide/en/elasticsearch/reference/7.x/search-request-body.html#request-body-search-sort)

In java, you can use a `FieldSortBuilder`: [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-search.html#\_specifying\_sorting](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-search.html#_specifying_sorting)
