You can use the savedsearch command to integrate any report (saved search) into another search.
If your report is named mysearch,
| savedsearch mysearch | where user="arobbins" or ip="127.0.0.1"
You can saved the result of your report as lookup table OR use summary indexing to save the result onto Splunk. Once you've done that, your report will be available to search via inputlookup command OR regular search over summary index used.
