RH2020: Include all words in search results = 0 results for merged/combined help
Upgraded from RH 2020.1 to RH 2020.3 (skipped over the .2 update and went straight to .3).
Generating Responsive HTML5 output with Azure_Blue.
Output is merged help, consisting of 1 parent and 11 child projects.
In RH 2020.1, end users could enter 2 or more search terms, select Include all words in search, and the search function would return results.
After upgrading to RH2020.3, if end users enter 2 or more search terms and select Include all words in search, they receive 0 results. Note that these are searches that returned results in the output generated in RH2020.1. End users only get results if the Include all words in search is NOT selected.

Note that curiously, the one match from my glossary is correctly (I have it intentionally enabled in our build settings) returned and displayed (I cropped out the definition in the attached image, but it displays correctly in the live system).
I generated a standalone (altogether different output preset) Responsive HTML5 Azure_Blue output for one of the child projects and the Include all words in search results function worked correctly. I tried creating a brand new output preset for my parent project, but still got the 0 results issue.
I exhausted a number of different tests - created new skins, created new build definitions, changed Search settings to try to get it to work, but no luck.
Thoughts?
