Pandora is a curated service. This means that we deliver material and their team of curators previews, screens, and considers the music to add to their service.
If you are searching your artist name and don't find it, it is because of this reason above as well. Your music won't always and automatically play when you find and search your name.
With that said, via the SymphonicMS, under the "Market" section. If you elect Pandora Expedite, you can send in a request to get your material on Pandora. Your request is compiled with that of others on a weekly basis, also reviewed, and if accurate, sent to Pandora for consideration.
Please keep in mind that Pandora curators look for the following when considering a release for a feature:
-Compelling album cover art
-Established, sizable audience reach
