Splunk Search

Can I create a multivalue _meta field?

Path Finder

I have a use case that uses an indexed field that is configured at input time:

_meta = new_field::value1

_meta = new_field::value1,value2

Is it possible to make new_field a true multi value field, so that a particular event could have a list of values and I can search on new_field=value1 rather than new_field=value1* or new_field=*value2?

Maybe not exactly what you're looking for, but for different sources / sourcetypes, you could add an EVAL in props.conf

EVAL-new_field = mvappend("value1","value2","value3")

Again, just one quick workaround.
