In the documentation, it shows how to specify a publicationID=xxx in the URL to get a citation list. I wonder if there's a way to do something like publicationID=xxx|yyy|zzz so that I can get all citations that cite any one of xxx, yyy, and zzz. I can
fire multiple queries to do it but I think it is more efficient to do so by one query. Likewise, it will be great if I can search full text by writing FulltextQuery=word1|word2|word3.
