Examples of org.apache.lucene.codecs.memory.DirectPostingsFormat$HighFreqDocsEnum

org.apache.lucene.codecs.memory.DirectPostingsFormat
Wraps {@link Lucene41PostingsFormat} format for on-diskstorage, but then at read time loads and stores all terms & postings directly in RAM as byte[], int[].
WARNING: This is exceptionally RAM intensive: it makes no effort to compress the postings data, storing terms as separate byte[] and postings as separate int[], but as a result it gives substantial increase in search performance.
This postings format supports {@link TermsEnum#ord}and {@link TermsEnum#seekExact(long)}.
Because this holds all term bytes as a single byte[], you cannot have more than 2.1GB worth of term bytes in a single segment. @lucene.experimental
