How to assign search_now value with info_max_time in _raw?

[LearningGuy]

Hello,

How to assign search_now value with info_max_time in _raw?

I am trying to push "past" data using collect command into summary index. 
I want to use search_now as a baseline time

I appreciate your help.  Thank you

Here's my attempt using some code from @bowesmana , but it gave me duplicate search_now:

index=original_index

| addinfo
| eval _raw=printf("search_now=%d", info_max_time)

| foreach "*"
[| eval _raw = _raw.case(isnull('<<FIELD>>'),"",
mvcount('<<FIELD>>')>1,", <<FIELD>>=\"".mvjoin('<<FIELD>>',"###")."\"",
true(), ", <<FIELD>>=\"".'<<FIELD>>'."\"")
| fields - "<<FIELD>>" ]

| collect   index=summary  testmode=false    file=summary_test_1.stash_new   name=summary_test_1"   marker="report=\"summary_test_1\""

I think I figured it out

index=original_index

| addinfo
| eval search_now=info_max_time
| eval _raw=printf("_time=%d", info_min_time)

| foreach "*"
[| eval _raw = _raw.case(isnull('<<FIELD>>'),"",
mvcount('<<FIELD>>')>1,", <<FIELD>>=\"".mvjoin('<<FIELD>>',"###")."\"",
true(), ", <<FIELD>>=\"".'<<FIELD>>'."\"")
| fields - "<<FIELD>>" ]

| collect   index=summary  testmode=false    file=summary_test_1.stash_new   name=summary_test_1"   marker="report=\"summary_test_1\""
