[solved] Issues was wrong file Too close to the trees to see the forest

[What I can do]

OS:Windows 10@64
Compiler: Lazarus 3.8
Project: Searching for words with in a TRichMemo document.
Every search works flawless except two
Document is a any standard Lazarus PAS file

Code: Pascal  [Select][+][-]

1.  L:=RichMemo2.Search('private',0,Length(RichMemo2.rtf),[]);
2. //retuns -1
3.  L:=RichMemo2.Search('public',0,Length(RichMemo2.rtf),[]);
4. //returns -1
5.   L:=RichMemo2.Search('procedure',0,Length(RichMemo2.rtf),[]);
6. //returns 1830 in my test document
7.   L:=RichMemo2.Search('type',0,Length(RichMemo2.rtf),[]);
8. //returns 387 in my test document
9.  
10.  

Update:
 I'm don't know if it's RichMemo2 or Lazarus because

Code: Pascal  [Select][+][-]

1.   L:=AnsiPos('private',RichMemo2.Lines.Text);
2.   L:=PosEX('private',RichMemo2.Lines.Text,1);
3.   L:=Pos('private',RichMemo2.Lines.Text);
4.  
5. //all returns 0

[What I can do]

tried to work around but it still too buggy

Code: Pascal  [Select][+][-]

1.   for L:=0 to 300 do
2.     begin
3.      str:=RichMemo2.Lines[L];
4.      i:=AnsiPos('private',Str); //never a successful test
5.      if I>0 then
6.       showmsg('good');
7.     end;

[What I can do]

interesting both of these return correctly

Code: Pascal  [Select][+][-]

1. L:=Pos('private','this has the word private');
2.   L:=ansipos('private','this has the word private');
3. // both return 19

so I'm leaning on the fault being TRichMemo

[What I can do]

Nope it's all my fault!
My boo boo
and after walking through line by line I finally found it
