I used to work at Atlassian but NOT on Confluence and I have no special information about this. But I can tell you that internally it is well known how awful the search is - they run one of the biggest known instances of Confluence - and there have been many spikes and projects to improve it. I have spoken to lots of people and asked why it continues to be so bad but all I get is handy-waving about how it's such a hard problem.

Honestly I wish I knew more but it was like pulling teeth trying to get people there to speak openly about why it's so hard when it is solved in so many other products.
