Working with two filters for one event row

[vtsguerrero]

I have one drop down and one text input, I need the user to be able to by both components OR INDIVIDUAL, one optional and they are both used for just one event row...

index=main source type=main_error ChannelCode=$channel$ OR ProcessCode=$process$

Can anyone explain this search string to me ?
Thanks in advance!

You can use the value as "*" for the dropdown/text box so that if User doesn't selects a filter, its default value * will be supplied.

E.g. dashboard

Updated

 <form>
  <label>DynamicChartTitle</label>
  <description>NULL</description>
  <fieldset autoRun="true">
    <input type="dropdown" token="sourcetype" searchWhenChanged="false">
      <label>Sourcetype</label>
      <choice value="*">All</choice>
      <default>*</default>
      <populatingSearch fieldForValue="sourcetype" fieldForLabel="sourcetype">
        <![CDATA[index=_internal earliest=-1h@h | stats count by sourcetype | table sourcetype ]]>
      </populatingSearch>
    </input>
    <input type="text" token="source" searchWhenChanged="true">
      <label>Source</label>
      <default>*</default>
    </input>
  </fieldset>
  <row>
    <table>
      <title>The chart tile</title>
      <searchString>index=_internal [|gentimes start=-1 
        | eval search=if("$sourcetype$"="*","","sourcetype=\"$sourcetype$\"")
        | eval search=case("$source$"="*",search, search !="",search." OR source=\"$source$\"",1=1,"source=\"$source$\"") | table search]
        | stats count by sourcetype, source</searchString>
      <earliestTime>-1h</earliestTime>
      <latestTime>now</latestTime>            
    </table>
  </row>
</form>

I had overlooked the OR condition between two filters. I have added some logic to handle that situation. Try the updated answer.

This is a good approach in general for the mentioned problem. But can't there be some side effects in this special case? Because the fields are combined with the OR operator.

When searching using a searchString, it's only searching if user choose a dropdown value and also type something in the text input, and I wanted to be able to search individually independent.

Do you mean "both the fields to be mandatory". In you search with that OR condition, even if user gives any one input the search will execute.

Sorry when I said filter, I meant two inputs...

[vtsguerrero]

It's only searching both mandatory :X
