How to exclude an item based on template when using find-item in Powershell

Question

I'm working on this script:

$criteria = @(
    @{Filter = "NotEquals"; Field = "_template"; Value = "{A87A00B1-E6DB-45AB-8B54-636FEC3B5523}"}  
)
$props = @{
    Index = "sitecore_master_index"
    Criteria = $criteria

}
Find-Item @props 

However I kept on getting this error:

Find-Item : Cannot bind parameter 'Criteria'. Cannot create object of type "Spe.Commands.Data.Search.SearchCriteria". Cannot convert value "NotEquals" to type "Spe.Commands.Data.Search.FilterType". Error: "Unable to match the identifier name NotEqual to a valid enumerator name.

I tried keywords for Filter such as: "Equals", "Equal", "NotContains" but still I kept getting the same error. Anynone could help me what's causing the issue? Basically I just want to exclude a certain items based on its templateid.

thanks

There is no NotEquals support for Filter.

But any condition can be negated if you use Invert = $true

$criteria = @(
    @{
        Filter = "Equals"; 
        Field = "_template"; 
        Value = "{A87A00B1-E6DB-45AB-8B54-636FEC3B5523}";
        Invert = $true;
    }  
)

I don't remember, maybe you need to lowercase and remove special chars from template ID: a87a00b1e6db45ab8b54636fec3b5523
