How to get relevance score from QueryBuilder?

To get the relevance score of a document to a particular query in AEM's QueryBuilder, you can use the setExplain(true) method to include the explanation of the score in the search results.

import javax.jcr.Session;
import javax.jcr.query.Query;
import javax.jcr.query.QueryManager;
import javax.jcr.query.QueryResult;
import com.day.cq.search.QueryBuilder;

// Get the QueryBuilder instance from the SlingHttpServletRequest object
QueryBuilder queryBuilder = slingRequest.adaptTo(QueryBuilder.class);

// Create a Map object for the query parameters
Map<String, String> queryParams = new HashMap<String, String>();

// Set the search term
queryParams.put("fulltext", "some query");

// Set the path to search
queryParams.put("path", "/content/my-site");

// Set the search type to "fulltext"
queryParams.put("type", "fulltext");

// Include the score explanation in the search results
queryParams.put("explain", "true");

// Execute the search
QueryResult queryResult = queryBuilder.createQuery(session, Query.XPATH, queryParams).getResult();

// Iterate through the hits to get the relevance score for each document
for (Hit hit : queryResult.getHits()) {
System.out.println(hit.getScore());
System.out.println(hit.getExcerpt());
System.out.println(hit.getPath());
}

In this example, queryParams.put("explain", "true") is used to include the explanation of the score in the search results. Then, hit.getScore() is used to retrieve the relevance score of each hit. Note that the Hit object is from the com.day.cq.search.result.Hit package.
