It's possible:
* The name is slightly misspelled: Double-check the spelling to see if you've made an error.
* The actress is new or less known: She might be a rising talent or work primarily in independent projects, which are harder to track down.
* The name is not associated with acting: Perhaps you're thinking of someone else with a similar name who's involved in a different field.
To help me find the right Ruby Visaria, could you please provide any additional information, such as:
* Her approximate age: Is she a child actress, a teenager, or an adult?
* Any other details you know about her: Does she have a specific appearance, or does she work in a particular genre of film or television?
* The country where she might be working: This could help narrow down the search.
With more information, I can provide a more accurate answer.
