org.apache.lucene.demo
static class: SearchFiles.OneNormsReader [javadoc | source]

java.lang.Object
   org.apache.lucene.index.IndexReader
      org.apache.lucene.index.FilterIndexReader
         org.apache.lucene.demo.SearchFiles$OneNormsReader

Use the norms from one field for all fields. Norms are read into memory, using a byte of memory per document per searched field. This can cause search of large collections with a large number of fields to run out of memory. If all of the fields contain only a single token, then the norms are all identical, then single norm vector may be shared.
