Hi,

I was investigating this issue and I think Jason is right — this modification could potentially fix the problem, even though it was originally meant to address a different issue.

However, I believe the main problem is that some changes were made to the schema.xml file of the Solr search core during the upgrade from version 7.2 to 8.0, and it's possible that this update hasn't been applied to the Solr instance you're currently using. I would also check that Solr is using the correct core definitions corresponding to the version you're running.

Specifically, I think you might be missing this line in the schema.xml you're using, which could explain the issue:

https://github.com/DSpace/DSpace/blob/main/dspace/solr/search/conf/schema.xml#L311

Best regards,

Toni

If you apply the changes to the two files, the browse function should be working fine.

        Hi Arpad,

        I have a DSpace instance (running 7.6.3) that has the same
        browse author behaviour that you are describing. Could you
        please let me know if you have discovered the cause of this
        (including if it was an indexing issue)?

        Thanks so much,
        Alex

            Hi Arpad,

            Considering this behavior doesn't occur on our demo site
            (https://demo.dspace.org), which is running the latest 8.x
            code, it does sound like it could be a possible indexing
            or configuration issue on your end.  If it was a bug in
            DSpace, it'd be more likely to appear (or be reproducible)
            on our demo site as well.

            Have you tried a full reindex of everything? "./dspace
            index-discovery -b"

            I'd recommend trying that, and perhaps also paying close
            attention to the backend logs *during* the indexing
            process to see if you are encountering a large number of
            errors.  If so, those might be clues as to what is going on.

            If you can find a way to reproduce this issue on our demo
            site, that might also provide more clues. You are welcome
            to even add some test content similar to your own content,
            if you think it could be somehow specific to your
            content/data.

            I don't have any other ideas, but it does sound like an
            indexing issue.  Such an indexing issue might be caused by
            a configuration problem, or possibly a local customization
            (if you've made any), or maybe even something went wrong
            in upgrading/migrating your configurations or
            customizations from DSpace 7 to DSpace 8.

                Hello Tim,

                That's right, this is the proper behaviour, there are
                no results because author names are unified (starting
                with last names), and there is no author name starting
                with "Kar..."

                We are facing a completely different issue. As I wrote
                in the post, it seems that the subject terms and
                author names are stored in the wrong format in the
                browse indexes.

                Let me show you some examples:

                *subject term in metadata (dc.subject field):
                Adriai-tenger*
                *subject term after filter results: adriaiteng*

                This wrong form of the subject term shows in the link,
                therefore, DSpace could not find the linked content:

                
https://digitalia.csfk.org/browse/subject?*value=adriaiteng*&bbm.return=1

                The proper link should be:
                
https://digitalia.csfk.org/browse/subject?*value=Adriai-tenger*&bbm.return=1
                (this link works just fine!)

                *author name: Allodi, Pietro*
                *filtered result after type "all" in the
                "Browse/Search" box: allodi*

                broken link:
                
https://digitalia.csfk.org/browse/author?*value=allodi*&bbm.return=1

                the correct link would be:
                https://digitalia.csfk.org/browse/author?*value=Allodi,
                Pietro*&bbm.return=1 (works fine)

                Global search (in the header or homepage) works perfect!

                Any idea to fix this issue?
                (Our database is not available to the public yet, only

                    Hi,

                    I believe this may be a misunderstanding on how
                    the "Browse by Author" pages work in DSpace.

                    When you visit the Browse By Author page in
                    DSpace, you'll see all the Authors in the system
                    listed alphabetically by surname (last name). This
                    can be seen on the demo site:
                    https://demo.dspace.org/browse/author

                    The "Browse/Search" box on that page notes
                    specifically that you can "Filter results by
                    typing the first few letters".  It is NOT a normal
                    search box, but rather allows you to immediately
                    filter that list of all Authors down to ones whose
                    surname begins with certain letters.

                    However, the *key point* is that box is expecting
                    you to type the author's *surname (last name)
                    first* , because that is how the authors are
                    listed in that "Browse by Author" page.

                    So, on the demo site, you can see that if you type
                    in "De" or "De Wael" you will *filter that list of
                    authors to only those whose surname starts with
                    that text.*
                    *
                    *
                    Therefore, typing "De Wael" in that box will
                    return two results:  "De Wael, K" and "De Wael,
                    Karolien"  See on the demo site:
                    
https://demo.dspace.org/browse/author?bbm.page=1&startsWith=De%20Wael
                    
<https://demo.dspace.org/browse/author?bbm.page=1&startsWith=De%20Wael>

                    However, if you instead type "Karolien", you will
                    receive *no results* because no authors in the
                    system have a surname of "Karolien"  See on the
                    demo site:
                    
https://demo.dspace.org/browse/author?bbm.page=1&startsWith=Karolien
                    
<https://demo.dspace.org/browse/author?bbm.page=1&startsWith=Karolien>

                    Keep in mind, the global search page will act
                    differently however.  If you type "Karolien De
                    Wael" in the global search (in the header or
                    homepage or search page), then you will get
                    results related to that author.  For example, on
                    the demo site:
                    
https://demo.dspace.org/search?query=Karolien%20De%20Wael&spc.page=1
                    
<https://demo.dspace.org/search?query=Karolien%20De%20Wael&spc.page=1>

                    This is expected behavior in DSpace because the
                    "Browse by Author" page only searches for author
                    names (surname first) that *start with* that
                    text.   But, the global search page will search
                    across the entire system for anything that matches.

                    I hope that helps to better explain the behavior
                    you are seeing.

                            Dear All,


                            We have some search issues on the browse
                            page using "search the repository' search
                            bar to filter the results.
                            Using the menu 'All of Dspace' > by
                            Subject > 'Search the repository', only
                            lowercase, truncated, and unaccented
                            subject terms are displayed, with broken
                            links (with the message 'no items to show')
                            E.g.:
                            *Adriai-tenger > adriaiteng*
                            *adatfeldolgozás > adatfeldolgoza*

                            The same issue occurs when searching for
                            authors on the browsing page. E.g.:
                            *Asztalos István > asztalo*

                             Using the "Search the repository" search
                            bar on the pages 'browsing by issue date'
                            and 'by title' works fine.
                            Could this be an indexing issue?
                            The links in the list of authors and
                            subject terms work fine. The issue only
                            occurs when we filter using the top search
                            bar on the browsing pages.

                            Dspace version: 8.0 (updated from 7.2)
                            Java version: 17.0.14

                            Could you please help solve this issue?
                            Any idea would be appreciated.
