# how to link sub-document with reference file for auto-completion in vim-latex?

I am writing a long document so I am making use of sub-documents and inserting them with \include.

The problem I am facing is that as the \bibliography{} line is on the main .tex file the sub-documents are not able to 'see' what is in the bibtex file, hence when I run the auto-completion function while editing the sub-document I cannot see the options for citing.

If I try the auto-completion function while editing the main.tex file I am able to see all the different options for citing.

How can I tell the sub-document to see that bibtex file too?

%\bibliography{bibtexfile}
