Yes, you can do that. Make a Query for the 30 papers and use that with your main query in a BooleanQuery if doing it programatically. Or with so few documents and papers to match, just in a long string via QueryParser. See http://lucene.apache.org/java/3_0_2/queryparsersyntax.html for details on query parser syntax - that is also the answer to your other question.
If performance is a concern and you will be reusing the same set of pubmed ids you should look at filters, specifically QueryWrapperFilter and CachingWrapperFilter. -- Ian.
