Method Detail

merge

public static void merge(org.apache.lucene.store.Directory srcIndexDir,
                         org.apache.lucene.store.Directory srcTaxDir,
                         org.apache.lucene.store.Directory destIndexDir,
                         org.apache.lucene.store.Directory destTaxDir)
                  throws IOException

Merges the given taxonomy and index directories. Note that this method opens DirectoryTaxonomyWriter and IndexWriter on the respective destination indexes. Therefore if you have a writer open on any of them, it should be closed, or you should use merge(Directory, Directory, IndexWriter, DirectoryTaxonomyWriter) instead.

Throws:

IOException

merge(Directory, Directory, IndexWriter, DirectoryTaxonomyWriter)

merge

public static void merge(org.apache.lucene.store.Directory srcIndexDir,
                         org.apache.lucene.store.Directory srcTaxDir,
                         org.apache.lucene.index.IndexWriter destIndexWriter,
                         DirectoryTaxonomyWriter destTaxWriter)
                  throws IOException

Merges the given taxonomy and index directories and commits the changes to the given writers. This method uses DirectoryTaxonomyWriter.MemoryOrdinalMap to store the mapped ordinals. If you cannot afford the memory, you can use merge(Directory, Directory, DirectoryTaxonomyWriter.OrdinalMap, IndexWriter, DirectoryTaxonomyWriter) by passing DirectoryTaxonomyWriter.DiskOrdinalMap.

Throws:

IOException

merge(Directory, Directory, DirectoryTaxonomyWriter.OrdinalMap, IndexWriter, DirectoryTaxonomyWriter)
