How to run a search with undefined token

Path Finder

I have a panel on a dashboard with a search using a token to exclude events with some field values.

Search is something like index=myindex sourcetype=mysourcetype $exclude$

The "exclude" token is generated from a checkbox input which generate a string like "myfield!=value1 myfield!=value2 ..."

This is working fine if at less one entry on checkbox is selected but a have the message Search is waiting for input...if no entries are selected.

I open the panel in search and see undefined on search bar.

Is it possible to run the search even if the token is not defined or to have an empty defined token if all entries on checkbox are unchecked?

if you set the token to nothing, it should work:

     <set token="exclude">&#32;</set>

and then did a

    <condition value="true">
       <set token="exclude">true</set>

however, this will always make exclude equal to something, so if you're using it in a depends statement, it won't work anymore. you'd need possibly eval a new token with condition match to make the depends work.

@ktn01, while you have not shared SimpleXML code for your checkbox, following is an example based on Splunk's _internal index.
I have defined introduced an empty checkbox choice None for Exclusion <choice value="">None</choice>, which is the default selection <default></default>

<input type="checkbox" token="tokExclude">
  <choice value="">None</choice>
  <choice value="log_level!=&quot;INFO&quot;">INFO</choice>
  <choice value="log_level!=&quot;ERROR&quot;">ERROR</choice>
  <choice value="log_level!=&quot;WARN&quot;">WARN</choice>
  <choice value="log_level!=&quot;FATAL&quot;">FATAL</choice>

Following is the query which runs on Splunk's _internal index:

      <query>index=_internal sourcetype=splunkd $tokExclude$
     | stats count</query>

| eval message="Happy Splunking!!!"
