Getting the position of a word via Solr API

Hi,
I am trying to retrieve from Solr API the position of a word from a text
field that was indexes but not stored.

I am storing the text field in an external repository and trying to do the
Solr built-in snippet function by myself, outside Solr.

Basically, all I need is to get from Solr the actual offset of the word in
the text.

I have tried 2 things:
1. Using the TermVectorComponent - Got NPE errors. 
2. Using Highlighting mechanism - didn't find the needed option in the API.

If one of this actually works, please tell me how :-)

Is there another way for me to get the location/position/offset of the
searched word from a text that is not stored in Solr?

Thank you very much!!

I would keep trying with the highlighters.  Some of them, at least, have 
options to provide an external text source, although you will almost 
certainly  have to write some java code to get this working; extend the 
highlighter you choose and supply its text from an external source.

Small update,
I have managed making the Term Vector to work and I am getting all the words
of the text field.

The problem is that it doesn't work with several words combined, I can't
find the offset of the needed expression starts...

Any ideas anyone?

Thanks!
