SegmentSuffix

Unique suffix for any postings files read for this segment. PerFieldPostingsFormat sets this for each of the postings formats it wraps. If you create a new PostingsFormat then any files you write/read must be derived using this suffix (use SegmentFileName(String, String, String)).

Declaration
public string SegmentSuffix { get; }
Property Value
Type Description
System.String

TermsIndexDivisor

The termInfosIndexDivisor to use, if appropriate (not all PostingsFormats support it; in particular the current default does not).

NOTE: if this is < 0, that means "defer terms index load until needed". But if the codec must load the terms index on init (preflex is the only once currently that must do so), then it should negate this value to get the app's terms divisor

Declaration
public int TermsIndexDivisor { get; set; }
Property Value
Type Description
System.Int32
