I would need to know more about your needs before I could make a reasonable recommendation. Are you trying to index just the headwords of your dictionary or all of the definitions (quotes, examples, etc.; see OEDV2 on CD to see what complete indexing is like). You mentioned a PDA: are you going to compress your data, either before or after indexing? Is speed of retrieval more important either space or time of indexing? Is the dictionary: static; slow growth only; adds and deletes? Does the indexing have to be done on the PDA or will it be done on some type of faster processor?
