Merge Queries by text contain

here an exemple of use of List.transformMany and a very basic Fuzzy compare function:

let
ruleList=Table.ToRecords(ruleTab),
tab=Table.FromRecords(List.TransformMany(dataTab[Titles], each ruleList,(x,y)=> if MyFuzzy(x,y[Titles]) then [Titles=x,Function=y[Function]] else [Titles=x,Function=null])),
    #"Rimossi duplicati" = Table.Distinct(tab, {"Titles","Function"}),
    #"Raggruppate righe" = Table.Group(#"Rimossi duplicati", {"Titles"}, {{"Func", each _[Function]}}),
    #"Valori estratti" = Table.TransformColumns(#"Raggruppate righe", {"Func", each Text.Combine(List.Transform(_, Text.From)), type text})
   in
    #"Valori estratti"

MyFuzzy:

let

myFuzzy=(fieldData,fieldRules)=> 

let
listRules=Text.SplitAny(Text.Lower(fieldRules)," -,"),

listData=Text.SplitAny(Text.Lower(fieldData)," -"),

fuzzyMatch=List.ContainsAny(listRules,listData)


in 
fuzzyMatch
in
myFuzzy

Here's my proudest work so far:

    #"Added Custom" = Table.AddColumn(Index, "Match", 
        (k) => Table.SelectRows(#"Assignments",
            each ([LocID]="*" or k[LocID]=[LocID])
                and ([PSA]="*" or k[PSA]=[PSA])
                and ([ST ID]="*" or k[ST ID]=[ST ID])
                )
            ),

This does a semi-fuzzy match across three fields of the two tables.
