Class Lucene46SegmentInfoFormat

Lucene 4.6 Segment info format.

Files:

• .si: Header, SegVersion, SegSize, IsCompoundFile, Diagnostics, Files, Footer

Data types:

• Header --> CodecHeader (WriteHeader(DataOutput, string, int))
• SegSize --> Int32 (WriteInt32(int))
• SegVersion --> String (WriteString(string))
• Files --> ISet<String> (WriteStringSet(ISet<string>))
• Diagnostics --> IDictionary<String,String> (WriteStringStringMap(IDictionary<string, string>))
• IsCompoundFile --> Int8 (WriteByte(byte))
• Footer --> CodecFooter (WriteFooter(IndexOutput))

Field Descriptions:

• SegVersion is the code version that created the segment.
• SegSize is the number of documents contained in the segment index.
• IsCompoundFile records whether the segment is written as a compound file or not. If this is -1, the segment is not a compound file. If it is 1, the segment is a compound file.
• The Diagnostics Map is privately written by IndexWriter, as a debugging aid, for each segment it creates. It includes metadata like the current Lucene version, OS, .NET/Java version, why the segment was created (merge, flush, addIndexes), etc.
• Files is a list of files referred to by this segment.
