Constructor CompressingTermVectorsFormat
CompressingTermVectorsFormat(String, String, CompressionMode, Int32)
Create a new CompressingTermVectorsFormat.
formatName
is the name of the format. this name will be used
in the file formats to perform
codec header checks (CheckHeader(DataInput, String, Int32, Int32)).
The compressionMode
parameter allows you to choose between
compression algorithms that have various compression and decompression
speeds so that you can pick the one that best fits your indexing and
searching throughput. You should never instantiate two
CompressingTermVectorsFormats that have the same name but
different CompressionModes.
chunkSize
is the minimum byte size of a chunk of documents.
Higher values of chunkSize
should improve the compression
ratio but will require more memory at indexing time and might make document
loading a little slower (depending on the size of your OS cache compared
to the size of your index).
Declaration
public CompressingTermVectorsFormat(string formatName, string segmentSuffix, CompressionMode compressionMode, int chunkSize)
