Can issue described in LUCENE-9981 be encountered with simple wildcard searches?

[Andy C <an...@gmail.com>]

Hi,

We are using Solr 8.8.2. An automated scan indicated that this version of
Solr is vulnerable to the issue described in
https://issues.apache.org/jira/browse/LUCENE-9981 where certain searches
can be extremely slow.

Does anyone know if this issue will only occur with true regular expression
queries? Our application allows the use of simple wildcards (*, ?), but
won't ever generate regular expression queries.

Also while I found discussion of the Solr regex query syntax elsewhere on
the web, I couldn't find any mention of it in the Solr Reference Guide. Is
there a reason for this?

Thanks,
- Andy -
