Seeking results of multi conditions in multi data column, but each condition value is just one of many in a single cell of google sheet

Please check the file first. https://docs.google.com/spreadsheets/d/1wYq9BEESpu77wvJzQY1AE4Gmr_PhhaNFSik0ZZt8aD0/edit?usp=sharing My purpose is:

• Generating idea randomly in "Calendar" sheet base on the "Idea" sheet The concept is:
• Selecting the condition about Industry & Quality in B1 & B2 in "Calendar" sheet
• Selecting the time will post on each day of week
• Then the idea will be shown off based on these conditions. In this case, any cell can has 2+ values.

We can't split values to single columns because those data can be added more value in future.
