Use score for natural sorting in Lucene

/*
* Here is the correlation ranking using Lucene
* Use score for natural sorting
* Correlation ranking is one of the simplest sorting methods.
* The so-called correlation is actually the score of the document
* The score of the document is different for each search,
* It needs to be determined based on the keywords found.
*
*TF Entry Frequency
*IDF Reverse Document Frequency
Incentive factors for *boost field

Document doc = Hits.doc (i);
The document to which it is matched
System.out.println (Doc.get ("bookname") + "\t\t");

Score from the document
System.out.println (Hits.score (i));

Here's how this score is going to be understood by explaining the method
System.out.println (Searcher.explain (q, Hits.id (i)). ToString ());
