Hi All,
I'm giving a talk at ApacheCon titled "Bet you didn't know Lucene can..."

for years the ActiveMath learning environment has been using as storage engine.
At the time (~2004), it was by far the best storage engine ever doable in a
pure java-world.
Now it still is perfect in terms of performance.
We had an issue with the separate versions where the stored-fields w

But: if you pass Version.LUCENE_31 when you create the

But it's better to use TieredMergePolicy (it's able t
Hi Grant,
Not sure if this qualifies as a "bet you didn't know", but one could use
Lucene term vectors to construct document vectors for similarity,
clustering and classification tasks. I found this out recently (although
I am probably not the first one), and I think this could be quite
useful.

My use case is the following :
Given an n-dimensional vector ( only +ve quadrants/points ) find its
closest neighbours. I would like to try out with lucene's default
ranking. Here is how a typical document will look like :
( or same thing
)
doc1 = 1245:15 3490:20 8856:20 etc.
As reflected in th
Hi Grant,
These are 2 cases into work i've done that I can think of:
-use Lucene to match products in a database with eBay auctions, the title
of the auction is used as the query to Lucene.
-use a servlet filter and Lucene to map well-formed URL's into a website
to it's individual (product) page
