Grant Ingersoll commented on SOLR-342:
--------------------------------------

Direct core meaning embedded, right?  It's interesting, b/c I have done a fair 
amount of Lucene 2.3 testing w/ Wikipedia (nothing like a free, fairly large 
dataset)

Can you reproduce the problem using Lucene directly? (have a look at 
contrib/benchmark for a way to get Lucene/Wikipedia up and running quickly)

Also, are there any associated exceptions anywhere in the chain?  Or is it just 
that your index is bad?  Are you starting from a clean index or updating an 
existing one?

> Add support for Lucene's new Indexing and merge features (excluding 
> Document/Field/Token reuse)

> LUCENE-843 adds support for new indexing capabilities using the 
> setRAMBufferSizeMB() method that should significantly speed up indexing for 
> many applications.  To fix this, we will need trunk version of Lucene (or 
> wait for the next official release of Lucene)
> Side effect of this is that Lucene's new, faster StandardTokenizer will also 
> be incorporated.  
> Also need to think about how we want to incorporate the new merge scheduling 
> functionality (new default in Lucene is to do merges in a background thread)
