I have the following query to be performed, where "STRING" is replaced across different queries. Is there a way to replace the STRING with a token and make it such that only 1 query is performed?
host="$host$" "STRING" | sort -_time | head 1 | eval time = _time
| eval sender = "STRING"
| table sender time
...
host="$host$" "STRING2" | sort -_time | head 1 | eval time = _time
| eval sender = "STRING2"
| table sender time
...
host="$host$" "STRING3" | sort -_time | head 1 | eval time = _time
| eval sender = "STRING3"
| table sender time
...
Simplify to be something like this where $sender$ is set to a dynamic value, but the following doesn't work.
<query id="masterQuery">
host="$host$" "$sender$" | sort -_time | head 1 | eval time = _time
| table sender time
</query>
...
<query base="masterQuery"> | eval sender = "xx" </query>
<query base="masterQuery"> | eval sender = "yy" </query>
Hi @denzelchung,
If you want your search to run only once and do further processing you can do with basesearch, where you add dynamic search content in child search rather than in base-search, hence your base search will be executed only once.
<query id="masterQuery">
host="$host$" | sort -_time | head 1 | eval time = _time
| table sender time *
</query>
...
<query base="masterQuery"> | search "$sender$"| eval sender = "xx" </query>
<query base="masterQuery"> | search "$sender$"| eval sender = "yy" </query>
But, as we are adding search command later most of the time searching all three queries requires less time than this base search as this base-search does not have more search criteria and will return lots of result to process.
So choose your approach wisely. Hope this helps!!!

Thank you! This is exactly that I'm looking for! I couldn't figure out how to do it.
@denzelchung it would be better if you explain what is the data you have and what is the output required. Seems like you are complicating the use case.
What is the reason to perform several queries, do you want to have separate visualization for each result? Have you tried Trellis Layout in this case?
Hi @niketnilay, I am trying to evaluate sender to be a fixed string. I have over 10 of these strings and I want 10 different individual visualization.
I don't think Trellis Layout fits my case as they cannot be split by sourcetype, host, etc.
