Primefree sequences in the OEIS. A bad idea.

[franktaw at netscape.net]

It would be useful to have some keyword-related searches in the advanced lookup.  (I'm referring to the keywords defined in the database here.)  I'd like at least the following:
 
* Search for a word, including only sequences with at least one keyword from a list.
* Search for a word, excluding any sequence which has any of a list of keywords.
* Search for a sequence of numbers, excluding any sequence which has any of a list of keywords.
* Search for a sequence of numbers, including only sequences with at least one keyword from a list.

...
It raises the necessity to have the possibility to "filter" the database
(for any personal scientific use). How to exclude <non-research sequences>
from a search?
