According to http://search.crossref.org/help/api we can send a query with a free form citation that may give us something back. We do this to get a list of candidates, and run a helm command to get the doi.

+* Adding a bibtex entry from a crossref query
+The idea here is to perform a query on Crossref, get a helm buffer of candidates, and select the entry(ies) you want to add to your bibtex file. You can select a region, e.g. a free form citation, or set of words, or you can type the query in by hand.
