Hi Jan,
Thanks for reporting this issue. I was "sure" it should work just as you expected because I know I am indexing those titles into the search index. But I just tried it on my machine and got the same result as you. I was able to figure out the problem and fix it so this will be fixed in the next release.
The technical explanation is that while I did have configured to index that content it was missing a needed additional setting for Field.TermVector.YES in configuring how those fields were indexed by the Lucene.NET search index.
After adding that and rebuilding my search index it now works as expected.
Best,
Joe
