 - I'm super curious to see how the JVM heap usage changes...
 - I made (and merged) a pull request to disable bot logging on the `5_x-prod` branch ([#387](https://github.com/ilri/DSpace/pull/387))
+- Now I'm wondering if there are other bot requests that aren't classified as bots because the IP lists or user agents are outdated
+- DSpace ships a list of spider IPs, for example: `config/spiders/iplists.com-google.txt`
+- I checked the list against all the IPs we've seen using the "Googlebot" useragent on CGSpace's nginx access logs
+- The first thing I learned is that shit tons of IPs in Russia, Ukraine, Ireland, Brazil, Portugal, the US, Canada, etc are pretending to be "Googlebot"...
+- According to the [Googlebot FAQ](https://support.google.com/webmasters/answer/80553) the domain name in the reverse DNS lookup should contain either `googlebot.com` or `google.com`
+- In Solr this appears to be an appropriate query that I can maybe use later (returns 81,000 documents):
+
+```
+*:* AND (dns:*googlebot.com. OR dns:*google.com.) AND isBot:false

+
+- I translate that into a delete command using the `/update` handler:

+- And magically all those 81,000 documents are gone!
