Filter one table based on contents of a second table

Anonymous  can you provide sample data and expected output in table format.

Here's one way using List.Accumulate to filter the column:

let
    Source = Excel.CurrentWorkbook(){[Name="Phrases"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Phrases", type text}}),

//Get keyword table and convert to list
    keyWords = Excel.CurrentWorkbook(){[Name="keyWords"]}[Content][Key Words],

//create list with matching rows
//  List.Accumulate creates the list
//  Table.FromColumns turns it back into a table
    filteredPhrases = Table.FromColumns(
    {List.Accumulate(#"Changed Type"[Phrases],{},(state, current)=>
        if List.ContainsAny(Text.Split(current," "),keyWords) then state else state & {current})},
        type table[Phrases=text])
    
in
    filteredPhrases

Add a filter step to your query and update the code in the formula bar along these lines:

= Table.SelectRows(#"Prev Step Name", (r) =>
    List.IsEmpty(
         List.Select(Animals[Animals], each Text.Contains(r[Phrases], _))
    )
)
