<li>I’m testing dspace-statistics-api with our DSpace 7 test server
<ul>
<li>After setting up the env and the database the <code>python -m dspace_statistics_api.indexer</code> runs without issues</li>
<li>While playing with Solr I tried to search for statistics from this month using <code>time:2022-09*</code> but I get this error: “Can’t run prefix queries on numeric fields”</li>
<li>I guess that the syntax in Solr changed since 4.10…</li>
<li>This works, but is super annoying: <code>time:[2022-09-01T00:00:00Z TO 2022-09-30T23:59:59Z]</code></li>

<ul>
<li>I tested the controlled-vocabulary changes on DSpace 6 and they work fine
<ul>
<li>Last week I found that DSpace 7 is more strict with controlled vocabularies and requires IDs for all node values</li>
<li>This is a pain because it means I have to re-do the IDs in each file every time I update them</li>
<li>If I add <code>id="0000"</code> to each, then I can use <a href="https://vim.fandom.com/wiki/Making_a_list_of_numbers#Substitute_with_ascending_numbers">this vim expression</a> <code>let i=0001 | g/0000/s//\=i/ | let i=i+1</code> to replace the numbers with increments starting from 1</li>

<li>That IP is on Internet Vikings aka Internetbolaget and we are already marking that subnet as ‘bot’ for XMLUI so most of these requests are HTTP 503</li>
