"New Group" > "Specified keywords" > "Generate groups for author last names" not working properly

[systemoperator]

When selecting "New Group" > "Specified keywords" > "Generate groups for author last names", providing any group name, entering "author" in the field "Field to group by" and clicking "OK", then hardly any (or even none) of the generated groups with the authors' last names have entries in it. Most badges have the value 0.

I'm using the latest JabRef 5 master build on Ubuntu 16.04.

This issue has been inactive for half a year. Since JabRef is constantly evolving this issue may not be relevant any longer and it will be closed in two weeks if no further activity occurs.

As part of an effort to ensure that the JabRef team is focusing on important and valid issues, we would like to ask if you could update the issue if it still persists. This could be in the following form:

• If there has been a longer discussion, add a short summary of the most important points as a new comment (if not yet existing).
• Provide further steps or information on how to reproduce this issue.
• Upvote the initial post if you like to see it implemented soon. Votes are not the only metric that we use to determine the requests that are implemented, however, they do factor into our decision-making process.
• If all information is provided and still up-to-date, then just add a short comment that the issue is still relevant.

Thank you for your contribution!

Issue still persists. Description has been updated.

Seems like JabRef creates group for the first name as well, but only fills the ones for the last names. I don't really understand how it's working

Should I look at it as part of the solution to #6394? I haven't looked at the details of this one but it would surprise me if it does not have overlap with the issues I am having updating the count badge and refreshing the content.

The scope of #7173 keeps expanding "naturally" anyway 😧

@k3KAW8Pnf7mkmdSMPHz27 If you find some time, it would be great.

There are multiple issues with getting this working properly and they are unfortunately not connected to #6394 so I won't continue with it for now, but these are my notes for now

1. The first problem is the use of KeywordListSearchStrategy in WordKeywordGroup, this means that any author with a "," before/after the last name is ignored (e.g., Turing, Alan should not be listed under "Turing")
   1. This particular issue can be relieved by using StringSearchStrategy but then other parts of the name will be matched as well, not only last names
   2. I believe there are issues where names containing latex also doesn't work, but I have not confirmed it (e.g., Gödel ≠ G{\"{o}}del)
      3. Is there a drawback to KeywordList being latex-free? (I don't remember how the global search deals with this issue)
2. The use of BibEntry#getLatexFreeField is not going to work in all cases (e.g., institutes)
3. Automatic keyword groups do not update in group list when keywords change #7129 should also be a problem in this issue (I have not confirmed this either)

If there is a point to making the "groups for author last names" slightly more accurate, switching to "StringSearchStrategy" is done by changing a boolean value. But it does not make the group work "properly".
