I noticed another thing: Suppose I search a folder called "[0 ] Experimental Methods". SIB doesn't find it. So I click on "show more results", it's there, I oper it and I open a file contained in it. After that, if I search for the same folder with Sib, it finds it. But still the results are different (worse) from what I obtain with "show more results" (or whathever i'ts called in english :-) ) David
