A mechanism is provided for improving search results. A user query is analyzed to identify a set of characters in the user query and an encoding code point associated with each character. A determination is made as to whether any of the encoding code points exist within a historic code point table. Responsive to at least one encoding code point existing within the historic code point table, all code points associated with each identified encoding code point in the user query are retrieved from the historic code point table. A modified user query is then created that utilizes the encoding code points of the user query and the code points from the historic code point table. The modified user query is then executed.
