Yes, it is still supported. Now, it gives more info:

Try swish-e -v 4 -D test.index

Ignore OFSETS INFO and HASHOFFSETS INFO. I use them for 
You will see something like this for the words (WORD INFO part):

myword: Meta:1 ./test_meta.html Rank:5800 Strct:7 Freq:2 Pos:3 

This means that the word "myword" is on MetaName 1 (No 
MetaName), in file ./test_meta.html, has a rank of 5800, a 
structure of 7 (like in 1.3.X). The frequency is 2 and the positions of 
the word in the file are 3 and 15.

The same info without -v 4 will look like:

myword: 1 8 5800 7 2 3 15

8 is the filenumber.

BTW, I use the positions for implementing phrase search.

Of course, for a word you can have several sets of this info. In this 
case, the information is sorted by metaname, filenumber.

All the words are sorted.
If you need more info let me know.
