No easy way unless you merge your 2 indexes into:
Index: [who] [accessed] [key] [content]
David 1/1/2007 Abc "blah blah 123 ..."
Someone 1/2/2005 Abc "blah blah 123 ..."
Guess 12/1/2000 Xyz "123 321 a nice day ..."
Harry 1/1/2008 Abc "blah blah 123 ..."
Sandra 1/1/2003 Xyz "123 321 a nice day ..."
Anyway, Lucene index is more like Database Index. It's only efficient for
particular query execution paths.
If you have special requirements, you will have to re-structure your index
for performance.
