Re: [EP-tech] Count mismatch on new views/fields created as subject

Hi Revathi,

The first thing to note is that a known bug in the counts for subject-tree based browse views has been fixed in a yet to be fully released version of EPrints:

https://github.com/eprints/eprints3.4/issues/323

This ensures that the number for the parent or greater ancestor subjects does not only count items in the currently selected child subject.  So as you navigate down the subject tree the counts for the parents/ancestors does not descrease.  However, this does not look to be the issue you are having here.

Secondly, it would not be unexpected for the sum of the counts of all the children in a subject tree to add up to a number either smaller or larger than the count listed next to the parent.  As one item could be under multiple child subject but can only be counted under the parent subject once.  Also, items could be only under the parent subject and none of the child subjects.

However, looking at you browse view screenshot you appear to have child subjects that have a higher count individually than their parent subjects.  This should not be possible.  I am not aware of any specific bug that would cause this.  However, browse view counts can behave oddly if you have a subject tree where the a subjects are link into the tree in multiple places.  If you could send me an export of you subject tree, I could determine if that would be an issue.  To export the subject tree you will need the command:

EPRINTS_PATH/bin/export ARCHIVE_ID subject XML > subjects.xml

This only exports the structure of the subject tree and not any information about publications, so should not contain any private information, unless you are using the subject tree for something other than options for fields that are the basis of browse views.

Dear all,
We have created a subject category with the following new fields and created views. 
May I know why the count is mismatching?
URL:

File name: /opt/eprints3/flavours/pub_lib/cfg.d/eprint_fields.pl
{
        name => 'subjects',
        type => 'subject',
        multiple => 1,
        top => 'subjects',
        browse_link => 'subjects',
},
{
        name => 'index_db',
        type => 'subject',
        multiple => 1,
        top => 'index_db',
        browse_link => 'index_db',
},
{
        name => 'study',
        type => 'subject',
        multiple => 1,
        top => 'study',
        browse_link => 'study',
},

Thanks
Revathi
