public class Completion090PostingsFormat
extends org.apache.lucene.codecs.PostingsFormat

This PostingsFormat is basically a T-Sink for a default postings format that is used to store postings on disk fitting the lucene APIs and builds a suggest FST as an auxiliary data structure next to the actual postings format. It uses the delegate postings format for simplicity to handle all the merge operations. The auxiliary suggest FST data structure is only loaded if a FieldsProducer is requested for reading, for merging it uses the low memory delegate postings format.

                                       String... fieldNamePatterns)

Returns total in-heap bytes used by all suggesters. This method has CPU cost O(numIndexedFields).

パラメータ:

fieldNamePatterns - if non-null, any completion field name matching any of these patterns will break out its in-heap bytes separately in the returned CompletionStats
