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.indexReaderFactory()
isearcher = IndexSearcher(ireader)
Kind of round about way to get an InstantiatedIndex I guess,but maybe
there's a briefer way?
Thank you.

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 InstantiatedReader or Writer, which take the
InstantiatedIndex as a constructor arg.
You should be able to just wrap that InstantiatedReader in a regular
Searcher.

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 query it like
before. What's the proper order to do this?
Also, if anyone has any empirical data on the performance or reliability
of InstantiatedIndex, I'd be curious.
Thanks for the tips!
