How can I Fix this Delegation Warning

[Qing]

Hey guys,
I'm having a "problem" with delegation. I've already gone through the numerous threads on this issue but they didn't help me find a workaround/other solution.
I'm currenly building a simple apps to query the data from sharepoint list.

For example, I'm using the following formula to filter the data by the user inputs. The warning occurs.How will I fix this? Any recommendations please. See the Screenshot for better understanding. Thank you very much

Set(
    Vstatus,
    Dropdown5.Selected.Ivalue
);
ClearCollect(
    MyRequestList,
    Filter(
        Contract,
        CurrentUserEmail = 'Requestor Mail',
        If(
            !IsBlank(Vstatus),
            Vstatus = 'Form Status',
            true
        ),
        If(
            !IsBlank(TextInput9.Text),
            StartsWith(
                'Form NO.',
                TextInput9.Text
            ),
            true
        )
    )
)

You'll need to recode those IF statements to do the same thing but using a slightly different method

Set(
    Vstatus,
    Dropdown5.Selected.Ivalue
);
ClearCollect(
    MyRequestList,
    Filter(
        Contract,
        CurrentUserEmail = 'Requestor Mail',
        !IsBlank(VStatus) = true Or Vstatus = 'Form Status',
        !IsBlank(TextInput9.Text) = true Or StartsWith('Form NO.',TextInput9.Text)
    )
)

Here's a link to my forum post a week ago where I helped with a similar issue.  I put my pattern for avoiding delegation there.  You can bookmark to it for future reference.

Another approach to fixing this that can be useful in complex filtering scenarios is to next the filters.  Since the delegation warning is only on one of the clauses in your filter you can also fix it by adding a filter within a filter.  Use the inner filter with the parts that don't cause a delegation warning.  If that will get your record count below the limit then you can safely ignore the warning.  In your case I suspect that the filter on current user alone may get you below the 500 record limit.  So you could try this filter.

Set(
    Vstatus,
    Dropdown5.Selected.Ivalue
);
ClearCollect(
    MyRequestList,
    Fliter(
        Filter(
            Contract,
            CurrentUserEmail = 'Requestor Mail'),
        If(
            !IsBlank(Vstatus),
            Vstatus = 'Form Status',
            true
        ),
        If(
            !IsBlank(TextInput9.Text),
            StartsWith(
                'Form NO.',
                TextInput9.Text
            ),
            true
        )
    )
)

That is not a solution, if the collect ton give the warning neither should the source, Microsoft needs to fix this give us a toggle or something.
