Stream - substitute result from output of a stream expr as filter query to another expr

[Susheel Kumar]

Hello,

How can we substitute an output from a streaming expr as a  filter query
inside another  streaming expression. For example below expr

select(
search(filters,
       q="*:*",
       fq="key:84396",
       qt="/export",
       fl="id,filter1_s,key",
       sort="key asc"
       ),
       filter1_s as filter)

outputs

{ "result-set": { "docs": [ { "filter": "division_s:(A B C)" }, { "EOF":
true, "RESPONSE_TIME": 4 } ] } }

and then how can apply the above filter value to below expr at runtime ? OR
How can we combine both below and above expressions and run as a single
streaming expression.
search(emp,
        q="*:*",
        fq=*"division_s:(A B C)"*,
        qt="/export",
        fl="id,name",
        df="_text_",
        sort="id asc")
Thanks,
Susheel
