I need a search which returns events where a specific field contains any one of many values. Typically this is done with the "OR" logical operator. However, I need to search for thousands of values which cannot be expressed using a regular expression.
I've seen discussions of using "lookups" for this. However, if I understand correctly, that would require administrative access to the Splunk server (which I don't have) to configure the lookup file and later update it.
I've also seen suggestions to write a script to generate a massive search string with all the "OR"s in it. I'd like to investigate other solutions before adopting that idea.
Ideally, I'd like to provide the list of field values to match in a file.
Is there a way?
Thanks,
Larry
You don't need administrative access to the Splunk server to create a lookup. You can use the GUI.
The instructions are in the Splunk Tutorial here

I confirmed that it is true that you can provision the lookup_file via manager. 🙂
I ended up using "... | lookup lookup_file.csv user_id_field as user | search tag_field = 1" where the lookup_file has two columns, user_id_field and tag_field". And each row contains a userid and a '1'.
Works great. Thanks!

Hello, thanks for your suggestion, but as mentioned in my question I have looked into lookups and I believe it would require administrative access to the Splunk server to configure (e.g. edit .conf file and upload lookup file to appropriate folder) and maintain (e.g. replace lookup file when the search terms change) the lookup files. This is something I do not have and cannot get.
Perhaps you can investigate the inputlookup / outputlookup methods of creating and maintaining a lookup file, e.g.
|inputlookup file | modify stuff | outputlookup file
