 - Dump and re-create indexes on AReS (as above) so I can do a harvest

+## 2021-06-16
+
+- Looking at the Solr statistics on CGSpace for last month I see many requests from hosts using seemingly normal Windows browser user agents, but using the MSN bot's DNS
+  - For example, user agent `Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.0; Trident/5.0;  Trident/5.0)` with DNS `msnbot-131-253-25-91.search.msn.com.`
+  - I queried Solr for all hits using the MSN bot DNS (`dns:*msnbot* AND dns:*.msn.com.`) and found 457,706
+  - I extracted their IPs using Solr's CSV format and ran them through my `resolve-addresses.py` script and found that they all belong to MICROSOFT-CORP-MSN-AS-BLOCK (AS8075)
+  - Note that [Microsoft's docs say that reverse lookups on Bingbot IPs will always have "search.msn.com"](https://www.bing.com/webmasters/help/how-to-verify-bingbot-3905dc26) so it is safe to purge these as non-human traffic
+  - I purged the hits with `ilri/check-spider-ip-hits.sh` (though I had to do it in 3 batches because I forgot to increase the `facet.limit` so I was only getting them 100 at a time)
+- Moayad sent a pull request a few days ago to re-work the harvesting on OpenRXV
+  - It will hopefully also fix the duplicate and missing items issues
+  - I had a Skype with him to discuss
+  - I got it running on podman-compose, but I had to fix the storage permissions on the Elasticsearch volume after the first time it tries (and fails) to run:
+
+```console
+$ podman unshare chown 1000:1000 /home/aorth/.local/share/containers/storage/volumes/docker_esData_7/_data
+```
