    That could be like this, our queries are

    Lookup keep as it is.

    In Main query add column with list of keywords by Text.Split() of Keywords field.

    Reference Lookup and create Not Contains keeping only Result and Not Contain columns, unpivot the latest, Group by Result without aggregation keeping only Values column. Thus we have list of Not Contain words for each Result (if exists)

    Similar for Contains

    Merge both above to have both lists in one List Combined table

    Reference Main query as Final, add above Lookup Combined table to new column here

    and expand it. 

    Add new custom column to check KeywordsList against Contains/Not Contains

    Group by initial columns without aggregation keeping in resulting table of each group only rows where previous value is true.

    Expand Result from it

    and finally combine with Prediction

    Details are in attached file.
