-Hi,
-
-I finished first steps to use Zebra as fulltext engine for Harvest
-(http://harvest.sourceforge.net/). The performance boost after
-some testing are quite impressive.
-
-Here is my article I wrote for the Harvest mailinglist.
-
-Many thanks for Zebra.
-
-------------------------------------------------------
-Hi,
-
-The first results after some testing with Zebra are very promising.
-
-The tests were done with around 220 000 SOIF files, which occupies
-1.6GB of disk space.
-
-Building the index from scratch takes around one hour with Zebra where
-Glimpse needs around five hours.
-
-While glimpse blocks search requests when updating its index, Zebra
-can still answer search requests.
-
-While the search time of glimpse varies from some seconds to some
-minutes depending how expensive the query is, Zebra usually takes
-around one to three seconds, even for expensive queries.
-
-Glimpse' index occupies around 250MB of disk space, Zebra's index
-takes around 570MB.
-
-Zebra supports incremental indexing which will speed up indexing even
-further.
-
-There are still potential for faster searches when necessary, using
-tweaks on apache.
-
-On the other hand, modeling data is not complete, yet.
-
-To sum it up:
-- Zebra indexes data five times faster than Glimpse
-- Zebra doesn't cause downtimes for indexupdate
-- Zebra's search time doesn't jump from seconds to minutes for no
- obvious reason, but stays constant within a range of one to three
- seconds
-- Zebra can search more than 100 times faster than Glimpse
-- Zebra can process multiple search requests simultaneously
-- Zebra can speed up indexing by using incremental indexing
-- Glimpse's index size is only around half of the Zebra's index

-Hi K-J,
-
-It's nice to read all this good stuff about Zebra! I'm currently
-working on changes to the documentation for the next Zebra release,
-and I'd love to include a lightly-edited version of your message in
-the new document. (Basically, I'd obscure the name of your old
-engine, so it's clear that we're trying to say good things about Zebra
-rather than score points off a competitor.) Would it be OK for me to
-quote you? If yes in principle, then I'll run the actual wording past
-you before submitting it.
-
-Thanks,
