it helps some times You could use Dictionary object:
code :
Sub test()
    Dim keywordColumn As String, productColumn As String
    Dim products As String
    Dim i As Integer
    Dim myKey, p

    'after adding reference to Microsoft Scripting Runtime
    'Dim Keywords As New Dictionary

    Dim Keywords As Object
    Set Keywords = CreateObject("Scripting.Dictionary")

    keywordColumn = "B"
    productColumn = "A"

    With ActiveSheet
        maxRow = .Cells(.Rows.Count, productColumn).End(xlUp).Row
        ' loop through each cell in the keywords column, ignoring the column header
        For i = 2 To maxRow
            ' the keywords are comma delimited so they must be Split()
            k = Split(.Cells(i, keywordColumn).Value, ",")

            For Each myKey In k
                If Not Keywords.Exists(myKey) Then
                    Keywords.Add key:=myKey, Item:=New Collection
                End If

                With .Cells(i, productColumn)
                    On Error Resume Next
                    Keywords(myKey).Add Item:=.Value, key:=CStr(.Value)
                    On Error GoTo 0
                End With                                        
            Next myKey
        Next i

        '**********************************************
        'OUTPUT
        '**********************************************

        i = 2
        'iterates through each key
        For Each myKey In Keywords.Keys                
            products = ""
            'iterates through each product corresponding to myKey 
            For Each p In Keywords(myKey)
                products = products & p & ", "
            Next
            'write in cells
            .Cells(i, "D") = myKey
            If products <> "" Then .Cells(i, "E") = Left(products, Len(products) - 2)

            i = i + 1
        Next

    End With
End Sub
Dim Keywords As New Dictionary
Dim Keywords As Object
Set Keywords = CreateObject("Scripting.Dictionary")
How do I search a dynamic object IEnumerable<dynamic> using a dynamically built lambda expression?

How do I search a dynamic object IEnumerable<dynamic> using a dynamically built lambda expression?

like below fixes the issue Since you know that the dynamic element of your query is actually ExpandoObject, hence IDictionary>, you can safely cast it to dictionary interface and use it to access the property values by name, while Enumerable.Any method can be used to simulate dynamic || condition:
code :
results = results.Where(r => r.PrimaryData.Contains(searchString)
    || optFieldList.Any(f =>
    {
        object value;
        return ((IDictionary<string, object>)r).TryGetValue(f.FieldName, out value)
            && value is string && ((string)value).Contains(searchString);
    }));

This might help you Case 1: Show list of productName in View while sending List productList in adapter constructor. , Check the type:
code :
@Override
public void onBindViewHolder(WhateverHolder holder, int position) {
    Object item = itemsList.get(position);

    if (item instanceof Products) {
        Product product = (Product) item;
        //populate the ViewHolder with the information
    } else if (item instanceof Category) {
        Category category = (Category) item;
        //populate the ViewHolder
    } else {
        throw IllegalArgumentException("Invalid item: " + item.getClass().getCanonicalName()); //this is optional 
    }
}

When list of search results is an object and one is chosen, ngtypeahead input shows [object][object]

To fix this issue Use inputFormatter to choose what you want to display from an object.
