Given a term "myterm", what kind of search algorithm lucene uses to
get to the postings list(i.e. the term-frequency location in .frq file)
? From what I understood by looking into the lucene fileformat, is that
it keeps the whole of .tii file in memory and and does a skipped linear
search of the TermInfoIndex(present in .tii file) for the term "myterm".
I have gone through Doug's article titled "Space Optimizations for Total
Ranking", but that seems to talk mainly about efficiently calculating
the score by parallely merging the different posting streams. I didnt
find any reference in that article on how to get to the postings, or may
be I overlooked something there ?
Any pointers will be greatly appreciated.
thanks,
prasen
