Splunk eval if with wildcard

Im trying to set a boolean based on a match in a string.
I want to set a value to 1 if it does not match ingestion* and set it to 0 if it does match.
The following example shows the problem:

index="balblableaw" 
| append 
    [| makeresults 
    | eval app_name ="ingestion_something"] 
| append 
    [| makeresults 
    | eval app_name ="should-match-only"] 
| eval not_contains_ingestion = if(app_name!="ingestion*",1,0) 
| table app_name, not_contains_ingestion

The expected result was that should-match-only would be 1 and the ingestion_something would be 0

@sboogaar,

Use match

index="balblableaw" 
 | append 
     [| makeresults 
     | eval app_name ="ingestion_something"] 
 | append 
     [| makeresults 
     | eval app_name ="should-match-only"] 
 | eval not_contains_ingestion = if(match(app_name,"ingestion"),0,1) 
 | table app_name, not_contains_ingestion

Try this:

index="balblableaw" 
 | append 
     [| makeresults 
     | eval app_name ="ingestion_something"] 
 | append 
     [| makeresults 
     | eval app_name ="should-match-only"] 
 | eval not_contains_ingestion = if(app_name like "ingestion%" ,1,0) 
 | table app_name, not_contains_ingestion

Thanks for the answer, can you explain why my own example was not working. I try to understand the disabilities from splunk.

In eval it doesn't treat * as wildcard but as literal
