I think the best way will be to pre-process the document (or use a custom UpdateRequestProcessor). Other option, if you'll only use the "cities" field for faceting/sorting/searching (you don't need the stored content) would be to use a regular copyField and use a "KeepWordFilter" for the "cities" field. However, with this approach it will be difficult to handle multi-word cities like "New York" or "Buenos Aires".
