Forward slash not handled correctly in MAR portal search queries

[mthalman]

There are a couple issues related to how forward slashes are handled in search queries on the MAR portal.

The first is that the query, https://mcr.microsoft.com/en-us/catalog?search=dotnet/framework/, produces an error: Sorry, we encountered an error. Please try again later.... The intent is that this query should find repos within the scope of mcr.microsoft.com/dotnet/framework/. Note that if you remove the trailing forward slash, the query works. However, it then does not provide the expected search results. This is the second issue. The forward slash doesn't seem to be interpreted literally. Because in the case of https://mcr.microsoft.com/en-us/catalog?search=dotnet/framework, it's returning back results for Azure Functions which are not within the scope of the dotnet/framework repo and, AFAICT, does not even include the term framework in its content.

Other interesting findings:

• Unlike https://mcr.microsoft.com/en-us/catalog?search=dotnet/framework/, using https://mcr.microsoft.com/en-us/catalog?search=dotnet/framework/&type=exact does return results, albeit with the second issue described above.
• https://mcr.microsoft.com/en-us/catalog?search=dotnet/&type=partial works but https://mcr.microsoft.com/en-us/catalog?search=dotnet/&type=exact produces an error.
