I am using bibtex4word to sort my references within my word documents. I've got a bib file created by Jabref to pick up my references.
Currently, I use the style "IEEEtran" to sort my references. This style is perfect for me since it sorts by order of appearance within the text. However, for multiple consecutive citations, I would like to further order by date. IEEEtran is not doing this. For instance if I have : "The reference  is better than these [2-4]."
I want my reference list to be :  A. aaa and B. bbb, blablabla, 2012  A. aaa and B. bbb, blablabla, 1980  A. aaa and B. bbb, blablabla, 2000  A. aaa and B. bbb, blablabla, 2018
In other word, I want the block [2-4] to be automatically ordered by date.
I tried to create a new .BST file to write my own ordering but I fail to do what I want. All I can do is sorting by date only or by appearence only...
Could someone help me on this? It seems difficult to understand these BST files...
