Has anyone else noticed a difference in SOSL on a Spring16 prerelease org? The code has not changed for over a year yet our custom search page has stopped finding results for search strings our end users commonly use.
We have compared our full copy to live (the only difference being the pre-release) and live still works as we expect.
Has anyone noticed this or maybe understand what could be the cause?
UPDATE
This was confirmed as a bug by Salesforce and was patched before the Spring16 release.
