类 ConstScoreQuery

java.lang.Object

com.alicloud.openservices.tablestore.model.search.query.ConstScoreQuery

所有已实现的接口:

Query

public class ConstScoreQuery
extends Object
implements Query

When we don't care about the impact of the retrieval term frequency TF (Term Frequency) on the ranking of search results, we can use constant_score to wrap the query statement query or filter statement, which improves the search speed.

Example: There are 100 people in our class, and there is a field called "name". We want to find people whose names contain "Wang", and we don't care about the sorting results. Using ConstScoreQuery (placing the original Query in "private Query filter;") will greatly improve the search speed.
