Limiting Software Enumeration

I would like to modify an existing dashboard to limit the Linux package that is being reported.  Specifically, I want to see any packages that start with kernel.  The plugin that is in use is Software Enumeration (SSH).  The existing query returns too many records and is truncated.  If I could limit it to see kernel packages only I think it would allow the query to complete.  Does anybody have any suggestions how to pass this kernel*?

I believe I figured it out:

index=server_logs sourcetype="tenable:sc:vuln" pluginName="Software Enumeration (SSH)" dnsName = "$server$"
| rex field=pluginText "Linux system\s\:\s+(?<RPM>[^<]+)"
| rex field=RPM mode=sed "s/\s+/;/g"
| makemv RPM delim=";"
| mvexpand RPM | search RPM="kernel*"
| table dnsName RPM
| dedup dnsName RPM

Unfortunately it includes any kernel-* items not just what I am looking for (i.e. kernel-3.10.*).  If I could limit it to kernel-3* and kernel-2* I think it would get what I need... Any way to do that?  Thanks!

Nice to hear that you figure it out. Probably this helps you to solve the rest?

Another option is | where match or like

I'm hoping this is what you are looking for:  (I'm a newbie).

index=server_logs sourcetype="tenable:sc:vuln" pluginName="Software Enumeration (SSH)" dnsName = "$server$"
| rex field=pluginText "Linux system\s\:\s+(?<RPM>[^<]+)"
| rex field=RPM mode=sed "s/\s+/;/g"
| makemv RPM delim=";"
| mvexpand RPM
| table dnsName RPM
| dedup dnsName RPM
