PubMed search fails due to stop/short words


I am using the PubMed search from within EndNote X5. I noticed that the search by title fails when I include certain stop or short words in the title of the paper.


Within EndNote, search PubMed using the following sentence in the “Title” filter:

Advanced sequencing technologies and their wider impact in microbiology

This produces no result.

Remove some of the stop words (removed “and their”):

Advanced sequencing technologies wider impact microbiology

Produces the right result.

Searching Pubmed directly using the entire title works fine.

This behavior is particularly annoying when adding references to Endnote from copy/paste of a title from a PDF or via the web.

Thank in advace for the help,
