More memory for Lucene

[Stefan Hinz <stefan.hinz@oracle.com>]

I've set up the first set of "real" docs for the WebHelp format. That 
is, some of our huge big MySQL docs are built in WebHelp format now, too.

This is done using the XSL 1.78.0 style sheets, which include the 
machinery for creating the WebHelp search index. All works remarkably 
well (thanks to the GSoC 2012 who implemented great improvements!), but 
there's one problem left which I haven't found a solution for.

When building on my local machine, creating the search index takes 
between 8 and 15 seconds, depending on the size of the book. On our 
central docs build machine, however, creation time is by factors higher 
(between 30 and 50 minutes!). I suspect that Lucene (the Java module 
that creates the index) needs more memory, or at least that would be my 
first try.

But how would I do that, i.e. allocate more than the default amount of 
memory (whatever it is) to Lucene? Any pointers appreciated!
