[EP-tech] Re: Possible Bug? Sort order in browse views. (in 3.3.10)

Hi Mark,

Thanks for the pointers on where to look....All fixed. 

Betsy, the changes I made, if you are interested....

I added an uppercase command into the file perl_lib/EPrints/Extras.pm, 

sub english_title_orderkey 
{
        my( $field, $value, $dataset ) = @_;

        $value =~ s/^[^a-z0-9]+//gi;
#      if( $value =~ s/^(a|an|the) [^a-z0-9]*//i ) { $value .= ", $1"; }

+      $value =uc($value);

        return $value;
}

I also commented out the "if( $value =~ s/^(a|an|the) [^a-z0-9]*//i ) { $value .= ", $1"; }" line as well, since management wanted things sorted by the complete titles name with a/an/the at the front.

Cheers

Matt

EPrints' DB is configured to do binary collation.  The standard way of modifying the sort behaviour would be to set make_single_value_orderkey for the title field and force the first letter to upper/lower case after switching the initial articles to the end.

Hi Betsy,

That makes sense now... The sorting (if I understand correctly) is using the eprints__ordervalues_en table and the field called 'title' contains details such as:

	Rigours of Teaching in 1930s, The
	Analysis of Sport Consumption, An
	rural party in an urban nation, A

I will look into the code a little today, and see if I can trace it, and force it to normalize case when performing the sort.

Cheers
Matt

Matthew,

We hadn't noticed this, but you're quite right about the two separate sort sequences, one following the other.  It looks to me like initial articles ("A", "An", "The") are being correctly ignored in both sequences; the difference is that the first significant word in each title in the first sequence begins with an uppercase letter, while the titles in the second sequence begin with a lowercase letter.  And all uppercase letters A-Z sort before all lowercase a-z.  This is easier to see on the Caltech page you link to, since there are more entries.

So whatever is creating the sort keys is correctly removing initial articles but failing to normalize case. I've had a quick look and can't find the code that creates the sort keys (it's past midnight here) -- will look some more in the morning.

Subject: [EP-tech] Possible Bug? Sort order in browse views. (in 3.3.10)

Hi All,

An academic has noted that the papers in their browse view aren't being listed in the correct order... eg (http://eprints.usq.edu.au/view/uniqueauthor/141.html within 2013, there are 2 at the bottom starting with 'A').  My initial thoughts were I had fudged something while I was reworking the AuthorID code into the browse 3.3.10 framework.  I checked http://authors.library.caltech.edu/view/year/1930.html as well, as they have a stock standard install of 3.3.10 and its happening there as well.

There appear to be two sorted lists that get stacked together.....
The first list is sorted correctly,
The second list contains titles that start with "A", "An", "The" which are sorted in the correct order (if you ignore the "A", "An", "The" at the front..)

Has anyone else noticed this?

Cheers

Matt
