Sometimes JSONata is so hard to understand...

how can i filter the string from the array that contains "bara" ?

```auto
["100.00barg","BAROMETER","101.00bara"]

```

Assuming that array is in `msg.payload`, the following will return an array that only contains the values that include the text `bara`

```auto
[
 $filter($.payload, function($v) {
   $contains($v, 'bara')
 })
]

```

Or without calling the filter function and to return an array even if single item found [Path Operators · JSONata](https://docs.jsonata.org/path-operators#---filter)

```auto
$$.payload[$contains($,"bara")][]

```

**$$.** payload[$contains( **$** ,"bara")]
