a. Search repos in an private organization should return repos if I'm sysadmin(even if I'm also owner or member of the organization), like it does without keyword or it does for normal members.

b. And found "user.id" shouldn't be use as parameter of sql here in sql log.

c.orderBy not work when ctx.IsSigned && !ctx.User.IsAdmin

d. SearchRepositoryByName use the same param OwnerID for search target and access check for org, and may not work well if they should be different.(Not the same as a, since sysadmin should simply skip all access check)
