Sort Collection of ScoreDocs
Is there an existing Utility class which will sort a collection of ScoreDocs
? I have a result set (array of ScoreDocs) stored in JVM and want to sort
them by relevanceScore. I do not want to execute the query again. The stored
result set is sorted by another term and hence the need.
Would highly appreciate if you would please let me know how do I do so?
Thanks,
-Chetan

Perfect Thanks.
Was also looking at org.apache.lucene.search.ScoreDocComparator

How about java.util.Arrays.sort() on the array using a simple
Comparator<ScoreDoc> with a compare() that returns -Float.compare(a.score,
b.score)? This is just about 7 lines of Java code.
