I'm trying to understand why my Solr index is not even touched when I delete my whole index!
So far I've tried a query directly to solr:
curl 'http://localhost:8080/solr/update?stream.body=<delete><query>*:*</query></delete>&commit=true'
I've also tried pysolr:
In [242]: from pysolr import Solr
In [243]: conn = Solr('http://localhost:8080/solr/')
In [244]: conn.delete(q='*:*')
The output of these two above commands is the same in catalina log.
No matter how I try this (even tried from the admin panel), the index still shows same number of docs:
Num Docs:
323
Max Doc:
323
Version:
52
Segment Count:
1
At first I thought it was a permission issue of my solr/data folder, but it was not. I commented out my cache in my solrconfig.xml, result was the same.
It would be great if anyone has any tips!
Later edit:
Everytime I run the above commands, only the files that have a later timestamp are modified (only from spellchecker dir) - you can also see that the user ownership is changed from www-data to root - when I manually run those commands

later later edit:
I tried to delete by id and it works! So for some reason deleting by
q=*:*
fails ...
I found out that the issue was in my schema.xml
I rewrote it and now works like a charm!
