# Class FixedGapTermsIndexWriter

java.lang.Object
org.apache.lucene.codecs.blockterms.TermsIndexWriterBase
org.apache.lucene.codecs.blockterms.FixedGapTermsIndexWriter

All Implemented Interfaces:
  `Closeable`, `AutoCloseable`

public class FixedGapTermsIndexWriter extends TermsIndexWriterBase
Selects every Nth term as and index term, and hold term bytes (mostly) fully expanded in memory. This terms index supports seeking by ord. See `VariableGapTermsIndexWriter` for a more memory efficient terms index that does not support seeking by ord.

WARNING: This API is experimental and might change in incompatible ways in the next release.
