I am using the following below for creating the IndexWriter (for my
indexing):
IndexWriterConfig indexWriterConfig = new
IndexWriterConfig(Version.LUCENE_40,
new LimitTokenCountAnalyzer(analyzer,
MAX_FIELD_SCAN_LENGTH));
if (create) { // create will be trure for indexing first time and later
will be false for updating the existing index
indexWriterConfig.setOpenMode(OpenMode.CREATE);
} else {
indexWriterConfig.setOpenMode(OpenMode.APPEND);
}
TieredMergePolicy mergePolicy = new TieredMergePolicy();
indexWriterConfig.setMergePolicy(mergePolicy.setNoCFSRatio(1.0d));
IndexWriter indexWriter = new IndexWriter(directory,
indexWriterConfig);
For creating the first time, index it is creating the following files:
_0.cfe
_0.cfs
_0.csi
segments.gen
segments_1
on subsequent updates, it is creating additional files like the below:
_0.cfe
_0.cfs
_0.csi
_1.cfe
_1.cfs
_1.csi
_0_1.del
_2.cfe
_2.cfs
_2.csi
segments.gen
segments_3
I am assuming that it should override the files initially created for
indexing:
should have just the following below files:
_2.cfe
_2.cfs
_2.csi
segments.gen
segments_3
Can someone please let me know if this is intended behavior or something
wrong with the way I am creating the IndexWriterConfig.
Appreciate if you could shed some light on this as the docs are not very
clear.
Thanks,
Sai.
