Thanks for your spontaneous response Mr.Chi. Though most of my queries are answered by your latest post, but I would still like to see one more thing in it. I saw that we can only search in title and abstract fields. If possible, then please extend the flexibility to search in claims, description and full text as well. By then, I would love to use this database.

The tools seems pretty good to me but I would have really enjoyed if this could have offered me to make more 'advanced' or 'complex' query construction.
