Hi Upayavira, Thank you for your analysis. I thought 'AND' & groupings are supported as per documentation:
http://docs.lucidworks.com/display/solr/The+Extended+DisMax+Query+Parser http://lucene.apache.org/core/old_versioned_docs/versions/3_5_0/queryparsersyntax.html#Grouping But yes, q=doc-id:3000 AND (-text:[* TO *]) works as expected.
