?SEARCHVIEW is not bringing back the expected results in 8.5.1

Last Saturday was a busy day. I made an upgrade from Domino 7.0 to Domino 8.5.1. Everything works fine until yesterday.
The design team told us that the ?Searchview with arguments doesn't work anymore.

So we start to search for a solution and found this APAR. The solution was simple "Dont use ?Searchview"  but i not agree with that.

I opened a PMR and the support team send the solution.

Put this line INOTES_WA_DISABLE_WEBSTYLE_SEARCH=1 on the notes.ini and the ?Searchview will work again

Thank's to Austin IBM SUPPORT
