Dear Andrzej Bialecki Can we change the field name in *.fnm directly by hand?

(note: this is a low-level hack, you can damage your index beyond repair). Take a look at FieldInfos class, and how it creates the *.fnm file for each segment. You can re-write these fnm files using new field names. In case of compound indexes you will need to "explode" them first to a non-compound format. Make sure you write out these files using exactly the same order of fields, otherwise you will end up in big trouble ;) -- Best regards, Andrzej Bialecki <>< ___. ___ ___ ___ _ _ __________________________________ [__ || __|__/|__||\/| Information Retrieval, Semantic Web ___|||__|| \| || | Embedded Unix, System Integration http://www.sigram.com Contact: info at sigram dot com --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] This e-mail and any files transmitted with it are for the sole use of the intended recipient(s) and may contain confidential and privileged information.
