IOContext |
DelCountOnFlush
Number of deleted documents set while flushing the segment.

Directory
Directory where this segment will be written to.
Declaration
public Directory Directory { get; }
Property Value

Directory |
FieldInfos
FieldInfos describing all fields in this segment.
Declaration
public FieldInfos FieldInfos { get; }

FieldInfos |
InfoStream
InfoStream used for debugging messages.
Declaration
public InfoStream InfoStream { get; }
Property Value

InfoStream |
LiveDocs
IMutableBits recording live documents; this is only set if there is one or more deleted documents.
Declaration
public IMutableBits LiveDocs { get; set; }
Property Value
Type | Description |
---|---|
IMutableBits |
SegmentInfo
SegmentInfo describing this segment.
Declaration
public SegmentInfo SegmentInfo { get; }
Property Value
Type | Description |
---|---|
SegmentInfo |
SegmentSuffix
Unique suffix for any postings files written 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 |
SegUpdates
Deletes and updates to apply while we are flushing the segment. A Term is enrolled in here if it was deleted/updated at one point, and it's mapped to the docIDUpto, meaning any docID < docIDUpto containing this term should be deleted/updated.
Declaration
public BufferedUpdates SegUpdates { get; }
Property Value
Type | Description |
---|---|
BufferedUpdates |
TermIndexInterval
Expert: The fraction of terms in the "dictionary" which should be stored in RAM. Smaller values use more memory, but make searching slightly faster, while larger values use less memory and make searching slightly slower. Searching is typically not dominated by dictionary lookup, so tweaking this is rarely useful.
Declaration
public int TermIndexInterval { get; set; }
Property Value
Type | Description |
---|---|
System.Int32 |
