Hi there-
I'm not sure what you've tried already but you have several options:
You can utilize Splunk's lookup functionality by:
a. write the data you want to save out to a csv file, using the outputlookup command, http://docs.splunk.com/Documentation/Splunk/latest/SearchReference/Outputlookup
b. read the data back in from the file using the inputlookup command, http://docs.splunk.com/Documentation/Splunk/latest/SearchReference/Inputlookup
Schedule the search that you've created, to extract your values, and choose to write them to a summary index. You can then search that summary index for the relevant values.
Although option 2 is valid, it may be overkill, depending on how you want to manage your data. I would start out with the first option and see if that does what you need it to.
