<p>It’s very likely that multiple values in a single field are being compared as an unordered set rather than an ordered list.

Try doing it in two imports. In first import, remove all authors. In second import, add them in the new order.</p>

<li>I restarted PostgreSQL (instead of restarting Tomcat), so let’s see if that helps</li>

<li>I filed <a href="https://github.com/DSpace/DSpace/issues/7989">a bug for the DSpace 6/7 duplicate values metadata import issue</a></li>

<li>I tested the two patches for removing abandoned submissions from the workflow but unfortunately it seems that they are for the configurable aka XML workflow, and we are using the basic workflow</li>

|
||
<ul>
|
||
<li>Looking at postgresqltuner.pl and <a href="https://pgtune.leopard.in.ua">https://pgtune.leopard.in.ua</a> I realized that there were some settings that I hadn’t changed in a few years that I probably need to re-evaluate</li>
|
||
<li>For example, <code>random_page_cost</code> is recommended to be 1.1 in the PostgreSQL 10 docs (default is 4.0, but we use 1 since 2017 when it came up in Hacker News)</li>
|
||
<li>Also, <code>effective_io_concurrency</code> is recommended to be “hundreds” if you are using an SSD (default is 1)</li>
|
||
</ul>
|
||
</li>

<li>I also enabled the <code>pg_stat_statements</code> extension to try to understand what queries are being run the most often, and how long they take</li>

<ul>
|

<li>Looking at the <code>EXPLAIN ANALYZE</code> plan for the query I noticed it wasn’t using any indexes</li>
|
||
<li>I <a href="https://dba.stackexchange.com/questions/103821/best-index-for-similarity-function/103823">read on StackExchange</a> that, if we want to make use of indexes, we need to use the similarity operator (<code>%</code>), not the function <code>similarity()</code> because “index support is bound to operators in Postgres, not to functions”</li>
|
||
<li>A note about the query plan output is that we need to read it from the bottom up!</li>
|
||
<li>So with the similary operator we need to set the threshold like this now:</li>
