How to add search bar to my created dashboard?

[ASR1022]

I have a dashboard created with network data already in that dashboard.  I am trying to create a search dropdown or search bar so I can search for a specific IP and it will show all the data for that IP in my dashboard.

If you're using simpleXML dashboards, then simply add a text form input and assign it a token and use that token in your search

<search>
  <query>your search... ip=$ip_text$</query>
</search>

Thanks, bowesmana,

I am new to Splunk I am trying to figure out the query for my search I am using a pivot search and when I put 

ip=$ip_text$

It tells me Error in 'PivotProcessor': Error in 'PivotCell': The dataset 'RootObject' has no field 'IP='.  I am wondering if I am doing the search wrong.

Are you using the pivot report and trying to add a filter or creating and classic (XML) or dashboard studio dashboard?
