Hi,
I can confirm that LE22AF01 is now found in more correction instructions (code changes) as text:
However, unfortunately still not in all relevant Notes... Note 2075938 is one interesting example. Launchpad corrections instructions (code changes) have "comment" part that contains LE22AF01 (at least when displaying), but it will not be found (for all release dates):
Another interesting effect can be seen when searching for FILL_DOC_TABLES - FILL_DESC_TABLE and fill_desc_table will be found as well:
I'd of course not mind some extra wrong/irrelevant hits... if that's the price to pay for finding more relevant hits 
. In this case the irrelevant finds can easily be filtered away by Component. When filtering on relevant Component IS-U-IN-PC, Launchpad leaves me with 4 Notes - all containing the search term used.
Which unfortunately is still less than the 7 Notes legacy application finds...
In summary: the search is better now, but there si still some work to do, I feel.
Thank you and best regards,
Janis
P.s. My next Launchpad challenge is: how do I get a list of all Notes relevant to Application Component/Area IS-U-IN-PC, within, say, last 3 years (I usually "need" those before upgrades, I order to get the feel of potential for "disruption" )?
I could do it in Legacy app using search, after enough filtering. This new app See what's new in the areas that interest you in Launchpad! is nice, but is restricted to 60 days at the moment.
