Hello,

I have logs like this :

`field1=value field2=value somedata==blablafoo field3=value`

I use kv to parse the logs.  
I have to remove double sign equal (==) because kv interpet this as a field, but when I use :

mutate {  
gsub =\> ["message", "[\=\=]", "" ]  
}

or

mutate {  
gsub =\> ["message", "[\==]", "" ]  
}

It remove ALL sign equal, and so kv filter is no more working.... Logs looks like :

`field1value field2value somedatablablafoo field3value`

I just want to remove only double sign equal.

Desired output :

`field1=value field2=value somedatablablafoo field3=value`

Have you some idea to figure this out ?

Thank you 🙂

Use =+, meaning one or more equals signs, and replace with a single...

```
mutate { gsub => ["message", "=+", "="] }

```

If the fact that that replaces a single equals sign with itself bothers you then you could use

```
mutate { gsub => ["message", "={2,}", "="] }
```

Thanks a lot @Badger ! This has solved my issue :

`gsub => ["message", "={2,}", ""]`

(personal reminder : read more clearly the documentation 😉 )
