Web.Contents Query parameter - multiple filed values for one parameter

The below code worked for me.

= let
    // List of subjects
    subjects = {
        "TEST1",
        "TEST2"
    },

    // Function to fetch data for a single subject
    getDataForSubject = (subject as text) =>
        let
            queryParams = [
                #"per_page" = "100",
                #"and[display_collection][]" = "test",
                #"sort" = "date",
                #"direction" = "desc",
                #"and[subject][]" = subject,
                #"APIToken" = "123"
            ],
             source = Json.Document(Web.Contents("http://api.test.org/v1/records.json?", [Query = queryParams]))
        in
            source,
            
       
subjectQuery = List.Transform(subjects, each getDataForSubject(_))
in
    subjectQuery
