How to run/optimize long ad-hoc searches with lookup

I'm trying to see if there are hits with Kaseya related domains in my Web datamodel. As I understand we need to use wildcard lookup or trim Web.url to match domains in  the lookup Splunk-REvil-Kaseya-IOCs/domains.csv at main · davisshannon/Splunk-REvil-Kaseya-IOCs (github.com)

What I've tried so far:

 

| tstats summariesonly=true latest("_time") values("Web.src") values("Web.dest") from datamodel="Web"."Web" by "Web.url" "Web.user"
| eval list="*"
| `ut_parse(Web.url, list)`
| lookup kaseya_domains domain AS ut_domain OUTPUT domain
| where isnotnull('domain')

 


It works, but not for a longer period of times (7 days or more). What are my options?
