Customize settings
You can change the settings in the limits.conf file, located in the etc/system/local directory, to adjust the search commands limitations to your needs.
If your environment has more than 50K forwarders, you can increase the sub-search result limit to be greater than the number of forwarders that you have. To increase this number, change the following setting:
# limits.conf in etc/system/local
[searchresults]
maxresultrows = <Default 50000>
[join]
Subsearch_maxout = <Default 50000>
