See details in this thread: http://maven.40175.n5.nabble.com/Search-with-several-artifacts-same-GAV-different-type-extension-td4902408.html
The key used by indexer is GAVC (GAV + classifier where classifier can be null).
With current design the indexer will only index one artifact with no classifier (= main artifact) + optionally additional secondary artifacts with classifier.
This is an issue for custom packaging types that publish several artifacts with different extensions but no classifier.
It would be good to include the extension in the index key => GAVCE. This way a search will return jar, tld and config artifacts.
