<p>Helping IFPRI with some DSpace 7 API support, these are two queries for items issued in 2024:</p>

|
||
</ul>
|
||
<p>Both of them return the same number of results and seem identitical as far as I can see, but the second one uses Solr date indexes and requires the full Lucene datetime and range syntax</p>
|
||
<p>I wrote a new version of the <code>check_duplicates.py</code> script to help identify duplicates with different types</p>
|
||
<ul>
|
||
<li>Initially I called it <code>check_duplicates_fast.py</code> but it’s actually not faster</li>

<li>I need to find a way to deal with duplicates from IFPRI’s repository because there are some mismatched types…</li>

<p>Continue working through alternative duplicate matching for IFPRI</p>
|

<ul>
|
||
<li>Their item types are sometimes different than ours…</li>
|
||
<li>One thing I think I can say for sure is that the default similarity factor in my script is 0.6, and I rarely see legitimate duplicates with such similarity so I might increase this to 0.7 to reduce the number of items I have to check</li>
|
||
<li>Also, the difference in issue dates is currently 365, but I should reduce that a bit, perhaps to 270 days (9 months)</li>
