search a text in a svn repository across all releases

问题

I need to search a text in a SVN repository, inside all revisions. I am trying this software, which indexes all repositories and then you can search:

http://www.supose.org/projects/supose/wiki

#create the index
./bin/supose  sc -U "svn://..." --username ... -p ... --fromrev 0 --create

#search
./bin/supose  se -Q "+contents:class"   

if i understood correctly, this should search across all files for the text "class". this should return a lot of matches, as there a lot of java files. however, it only returns maches in some .xml; it is ignoring java files. why?

and what is the "search --fields" option? what is a field?
