*23032* should work
Except if 0 (number) is misinterpreted and OCRed as O (letter O) 0, 8, B, i, l for instance are good candisates for misinterpretation with OCR engine
Try different value without 0
If nothing is found, sounds like a problem with fulltext on your DW organization, you should open a SR, fulltext might be broken on your organization.
