Can't I use the 'IN' or 'LIKE' statement in a filter? If not I guess I have to make an SQL Query? If I can,what's the syntax? Delphi is very persistent in telling me I'm trying to do something stupid....

Unfortunatley, there really ins't a equivelent function to LIKE or IN with filters, but you may be able to use the setRange function.  You can use the setRange to filter on words that say start with 'A' which would bring back Ann, Abe, etc.  The full syntax for SetRangeStart - SetRangeEnd and ApplyRange are in the Help manual, but I provided an example below.  If you have any questions, please add a comment.

with Table1 do
  begin
    SetRangeStart; { Set the beginning key }
    FieldByName('City').AsString := 'Ben Lomond';
    SetRangeEnd; { Set the ending key }
    FieldByName('City').AsString := 'Scotts Valley';
    ApplyRange; { Tell the dataset to establish the range }
  end;

For more specific filter, you will have to use a Query.

Good Luck!

On more thing, I left out the syntax to find all the 'A's I mentioned before.  It is,

With Table1 do begin
 IndexName := 'secind';
 SetRangeStart; //Starts setting the starting values
 FieldByName('FirstName').asstring := 'A';
 SetRangeEnd; //Starts setting the ending values
 FieldByName('FirstName').asstring := 'A' + #255; // All A's
 ApplyRange;
end;
