This issue is resolved.  The trick is, use setField function , and as argument pass key and an array containing multiple values. That way previous old values are deleted and new values takes effect (by default it is 2 minutes to take effect).

If one uses addField function, you will never be able to delete the old value, hence wrong data in index.

Dear Earnie Boyd
Thanks for response.

I have gone through those few times. These are links, that says how to setup and get it to work drupal/solr stuff.
However it does not give much insight how to do reset multi-value fields in index.

I expect the silence is due to the lack of individuals with experience
in the combination on this list.
