Since the store has no specific way to show applications only to a specific publisher, search is an affordable option. Since you have found that there is no way to hint at a search that the term provided is the name of the publisher, it can bring up other things. One hack that I saw is used to add a custom keyword to all applications by the publisher, who is likely to be unique and looking for it. Something like "apps-by-code-next." Search is currently raising keywords, and this value is unlikely to appear in other applications.
Alternatively, you can provide a better experience by directing people to the applications listed on your own website. This may contain relevant links to specific applications in the store. As the publisher has more and more applications, it is less likely that everything will be relevant to the person using one of them. It may be more appropriate to show only relevant applications (relative to the obe used) that are directly related to the store. Yes, it may be more work, but it gives you, the publisher, more control and, hopefully, people using applications with better experience.
