Using Eval to Filter Values

[jason_hotchkiss]

Hello Splunkers - 

I am trying to filter any value that is wrapped in $, such as $host$or $value$.  I thought the below would work, but it is not.  Can someone point out what I am doing wrong?  Thanks!

| eval dollar_sign=if(host_value=="$host$" OR host_value=="$value$", "yes", "no")
| search NOT dollar_sign=yes

If you are using this in a dashboard, the dollar signs have to be doubled up otherwise it is looking for tokens

| eval dollar_sign=if(host_value=="$$host$$" OR host_value=="$$value$$", "yes", "no")
| search NOT dollar_sign=yes

I will keep this in mind if I end up using this in a dashboard.  Thank you @ITWhisperer

| eval dollar_sign=IF(LIKE(host_value, "$%$"), "yes", "no")
