Search Keywords in Documents in SharePoint

Hi, I am currently creating a power app to search policy documents in SharePoint. I am able to search the documents name using the below code:

If(
    (IsBlank(Dropdown3.Selected.Value)),
    Search(
        Filter(
            Documents,
            !IsFolder
        ),
        TextInput2_1.Text,
        Name,
        'Link to item',
        Title
    ),
    With(
        {
            _Data: Filter(
                Documents,
                'Type of Policy'.Value = Dropdown3.Selected.Value
            )
        },
        Search(
            Filter(
                _Data,
                !IsFolder 
            ),
            TextInput2_1.Text,
            Name,
            'Link to item',
            Title
        )
    )
)
 
To search through the documents for keywords, I have to create a power automation flow. The flow works correctly alone in a gallery when I putTable(ParseJSON(varSearchResults.searchresults))
 
 
I want to add the above line to my if statement so it can search the document name and for keywords but when I add it to my filter line, it does not look for keywords. It still only search the name. The code I am trying to use is below:
If(
    (IsBlank(Dropdown3.Selected.Value)),
    Search(
        Filter(
            Documents,
            !IsFolder, ParseJSON(varSearchResults.searchresults)
        ),
        TextInput2_1.Text,
        Name,
        'Link to item',
        Title
    ),
    With(
        {
            _Data: Filter(
                Documents,
                'Type of Policy'.Value = Dropdown3.Selected.Value
            )
        },
        Search(
            Filter(
                _Data,
                !IsFolder,ParseJSON(varSearchResults.searchresults)
            ),
            TextInput2_1.Text,
            Name,
            'Link to item',
            Title
        )
    )
)
