It's possible:
* The name is misspelled: Double check the spelling and try searching again.
* The author uses a different name: Perhaps she publishes under a different name or a pseudonym.
* The author is less well-known: Not all authors are widely recognized. She may have published works that aren't widely available or easily discoverable online.
To help find more information, it would be helpful to know:
* What kind of writing are you looking for? (fiction, non-fiction, etc.)
* Do you have any additional information about the author? (approximate time period of writing, any known titles, etc.)
With more details, it might be easier to find the author you're looking for.
