I'm running a query like:
index=my_index [search index=my_index abcd|table x] |table y
This works out well, but in the job details i see the following message multiple times:
INFO StringSearchExpander - calculated_field="x" not expanded in comparison_expression="x="blahblah"". calc_field_processor!=null, negated=false (negation depth=0)
Can anyone explain what it means and if it impacts the output of my query?
The best approach for subsearch filter is to use the return function:
|return 100 x -> return one field named "search" with first 100 values in one row, field name included:
"x=value1 OR x=value2 OR x=value3"
|return 100 $x -> return one field named "search" with first 100 values in one row, no field name included:
"value1 OR value2 OR value3"
