"this is probably *not* as much a store related.." that is.

The actual performance depends on how much you load to the index. Can
you tell us how many documents and how large these documents are that
you have in your index?
Compared with RAMDirectory I'vee seen performance boosts of
up to 100x in a small index that contains (1-20) Wikipedia sized
document
After I switched to InstantiatedIndex from RAMDirectory (but using the
reader from my RAMDirectory to create the InstantiatedIndex), I see a
less than 25% (.25) improvement in speed. Nowhere near the 100x (100.00)
speed mentioned in the documentation. Probably I am doing something
wrong.

Yeah. That makes sense. Its not too hard to wrap those extra steps so I
can end up with something simpler too. Like:
iindex = InstantiatedIndex("path/to/my/index")
I'm lazy so the intermediate hoops to jump through clutter my code.
Hehe.

Can you start with an empty index? Then how about:
// Adding these
iindex = InstantiatedIndex()
ireader = iindex.indexReaderFactory()
isearcher = IndexSearcher(ireader)
If you want a copy from another IndexReader though, you have to get that reader
from somewhere right?

Hi Mark,
Thanks for the tips. Here's what I will try (psuedo-code)
endirectory = RAMDirectory("index/dictionary.en")
ensearcher = IndexSearcher(endirectory)
// Adding these
reader = ensearcher.getIndexReader()
iindex = InstantiatedIndex(reader)
ireader = iindex.indexReade
Check out the docs at:
http://lucene.apache.org/java/2_4_0/api/contrib-instantiated/index.html
There is a performance graph there to check out.
The code should be fairly straightforward - you can make an
InstantiatedIndex thats empty, or seed it with an IndexReader. Then you
can make an Inst
Hi gang,
I am trying to trace the 2.4 API to create an InstantiatedIndex, but
its rather difficult to connect directory,reader,search,index etc just
reading the javadocs.
I have a (POI - plain old index) directory already and want to
create a faster InstantiatedIndex and IndexSearcher to q
