I am trying to create an index of the personal and file geodatabases on my system. I can use FileInfo and DirectoryInfo to do so, but I'd rather do this using ArcObjects components if possible. I'd like to believe there's a way to tap into ArcCatalogs search index, but so far I haven't seen anything that provides a way to do this. As a fall back I have been working with the CatalogSearchEngineClass, ISearchEngine and FileSystemQuery but have run into many problems. First and foremost there does not seem to be an "INativeType" for geodatabases - leading me to think the whole assemblage was written back at version 8 and never updated? This belief is strengthened by the fact that the catalog search doesn't seem to know what a geodatabase is as it drop into gdb folders and then into featuredatasets as if they were just another subfolder! If you have any experience searching using ArcObjects please reply!
