Visual Needed

Hello,

Is there a filter available where the end user can type a word and have it filter a field to "contains" that word? Our marketing team has launched several campaigns and they put key words into the notes of the activities in order to filter reporting in excel. I'd like to put it in a Power BI report where they can type into a field and it will filter all activity notes with "contains" whatever word they type in. Any thoughts on how this can be accomplished?

Thanks!
