## 2019-11-15
- Run the new version of `check-spider-hits.sh` on CGSpace's Solr statistics cores one by one, starting from the oldest just in case something goes wrong
- But then I noticed that some (all?) of the hits weren't actually getting purged, all of which were using regular expressions like:
- `MetaURI[\+\s]API\/[0-9]\.[0-9]`
- `FDM(\s|\+)[0-9]`
- `Goldfire(\s|\+)Server`
- `^Mozilla\/4\.0\+\(compatible;\)$`
- `^Mozilla\/4\.0\+\(compatible;\+ICS\)$`
- `^Mozilla\/4\.5\+\[en]\+\(Win98;\+I\)$`
- Upon closer inspection, the plus signs seem to be getting misinterpreted somehow in the delete, but not in the select!
- Plus signs are special in regular expressions, URLs, and Solr's Lucene query parser, so I'm actually not sure where the issue is
- I tried to do URL encoding of the +, double escaping, etc... but nothing worked
- I'm going to ignore regular expressions that have pluses for now
- I think I might also have to ignore patterns that have percent signs, like `^\%?default\%?$`
- After I added the ignores and did some more testing I finally ran the `check-spider-hits.sh` on all CGSpace Solr statistics cores and these are the number of hits purged from each core:
- statistics-2010: 113
- statistics-2011: 7235
- statistics-2012: 0
- statistics-2013: 0
- statistics-2014: 316
- statistics-2015: 16809
- statistics-2016: 41732
- statistics-2017: 39207
- statistics-2018: 295546
- statistics: 1043373
- That's 1.4 million hits in addition to the 2 million I purged earlier this week...
- For posterity, the major contributors to the hits on the statistics core were:
- Purging 812429 hits from curl\/ in statistics
- Purging 48206 hits from facebookexternalhit\/ in statistics
- Purging 72004 hits from PHP\/ in statistics
- Purging 76072 hits from Yeti\/[0-9] in statistics
- Most of the curl hits were from CIAT in mid-2019, where they were using [GuzzleHttp](https://guzzle3.readthedocs.io/http-client/client.html) from PHP, which uses something like this for its user agent:
```
Guzzle/<Guzzle_Version> curl/<curl_version> PHP/<PHP_VERSION>
```
- Run system updates on DSpace Test and reboot the server
