True in the worst-case (cold disk cache). If you have warm-up and only use this technique judiciously (on a few docvalues fields), then one can assume the data is cached. And you can explicitly use a memory based DV format too, which puts all the values in a memory-efficient FST assuming string/text data. ~ David Smiley Freelance Apache Lucene/Solr Search Consultant/Developer http://www.linkedin.com/in/davidwsmiley
