IndexSorter (Lucene 3.6.2 API)

java.lang.Object
- org.apache.lucene.index.IndexSorter

```
public class IndexSorter
extends Object
```
Sort an index by document importance factor. Higher scoring documents are assigned smaller document numbers. Document weights are obtained from a specified field, which has to be single-valued and stored, with string value that represents a float number. Stored fields in the output index remain consistent, i.e. both stored fields and postings are renumbered in sync.
NOTE: this tool is unaware of documents added atomically via IndexWriter.addDocuments(java.util.Collection<org.apache.lucene.document.Document>) or IndexWriter.updateDocuments(org.apache.lucene.index.Term, java.util.Collection<org.apache.lucene.document.Document>), which means it can easily break up such document groups.
