Just want to clarify what you are saying ...

In the current design, learning outcomes are not displayed within search =
results.  Instead, a link to "related outcomes" appears in the brief =
metadata for each search result.  The related learning outcomes for the =
learning object could be calculated when this link is clicked.

Are you suggesting that the cost of calculating matching learning =
outcomes when this link is clicked is too high, and therefore they =
should be pre-calculated for each learning object?

If pre-calculation is required, then I think calculation has too happen
A) When a learning object (version) is loaded
B) When the curriculum organiser is changed

(A) involves a calculation for just new learning objects (and versions).
(B) involves a re-calculation for every learning object.  Presumably =
this could take a while if there are a large number of objects.
