Hi all,
I'm curious as to whether MultiSearcher (as of 1.9) does a good job
of blending search results, when the various indexes being searched
have significantly different characteristics.
For example, let's say I've got two indexes. One consists of
documents where the term "platypus" almost never occurs. This index
will have a very high IDF for that term.
The second index happens to be from the portion of the crawl that was
covering biology departments in Australian universities, so the term
"platypus" is significantly more common.
If I do a search on "platypus lifespan" using MultiSearcher, will
hits from the first index get an unnatural boost because of the
corresponding high IDF in that particular slice of the data? Or
should I expect that the results will (closely) match what I'd get
back if I merged the two indexes and used a regular searcher?
Thanks,
-- Ken
