Auto search does not work in Horde Address Book. Example, when I type 'DM - ' in the "to:" field, Auto Search form address book shows me the list of accounts like this:
So it includes addresses that should not be shown.
Horde searches any words in address book that are separated by space sign, i.e.:
- 'DM' will show all entries with DM mail name like "DM" firstname.lastname@example.org
- 'DM -' will show all entries where there is DM or - in the mail name description, that is why you see both. If you would like to see only "DM -" mail account, please type them in double quotes like "DM -"
