yeah but its a very important one thats missing compared to 0.6 TST

I also dont think fts:snippet is the right way to do that as 0.6 TST
used a spearate dbus call so it could be fetched async after the results
were displayed (otherwise slow snippets would seriously slow down
display of results)

sqlite fts returns the positions and metadata field for a hit so it
should be easy to do. All thats needed is to expose fts:positions in
sparql and provide a dbus method to get text from a position, metadata
field and ID
