Hi, I've been trying to understand Lucene's file format and I keep getting hung up on one detail - how can Lucene quickly find the frequency data (or proximity data) for a particular term? According to the file formats page on the Lucene website<http://lucene.apache.org/java/2_2_0/fileformats.html#Term%20Dictionary>, the FreqDelta field in the Term Info file (.tis) is relative to the previous term. How is this helpful? The few references I've found on the web for this subject make it sound like the Term Dictionary has direct pointers to the frequency data for a given term, but that isn't consistent with the aforementioned reference.
Thanks for your help, Gio.
