Kim Haase commented on DERBY-6564:
----------------------------------

The functional spec is for the most part really clear -- thanks, Rick. I have a few questions
here and there, though:

Under "Terms" --

score -- what are the minimum and maximum values? is it like a percent (0 to 100)? or 0 to
1.0?

keycolumns -- comma-separated list, I gather?

Under "Querying an index", a line in the returned table says

 DOCUMENT ID INT,
 
This is supposed to be

 DOCUMENTID INT,
 
isn't it?

I thought with a score the higher values indicated a better match. So why would you only want
to return results with scores *under* a certain value (SCORECEILING)? And what would specifying
a SCORECEILING of 0 do? I thought it would produce no results.

Under "Classpath" -- Where do you get the Lucene jars?

Thanks!
