they key would work as an offset
imagine
{autosentece m,M,offset}
Where the component output is something like
2014/06/06 Search . Lorem ipsum....
Here, I would like to have the description as
Lorem ipsum...
Because the first part would be meaningless for me. So maybe I would like to have something like
{autosentence 90,120, 20}
So the macro only gets from "Lorem Ipsum" and later, but not the search
The problem with this approach is that the offset would need to be fixed and so it wouldn´t have a lot of flexibility. So the next logic improvement would be
{autosentence 90,120,<!--fromhere-->}
and I would modify my article template like
2014/06/06 Search .<!--fromhere--> Lorem ipsum....
Did I explain better?
