A method performed by a computing device for searching for analog data corresponding to an analog annotation within a file, comprising: maintaining an analog writing database, a facial expression database and a voice database, comprising respectively analog writing entries, facial expression entries, and voice data entries, each of the entries in the analog writing database, facial expression database and voice database corresponding to an analog annotation within a given file and being stored in association with a file tag identifying a given location of the analog writing entry, facial expression entry, and voice data entry within the corresponding given file; maintaining an analog writing mapping database, a facial expressions mapping database and a voice mapping database, the analog writing, facial expressions and voice mapping databases (364, 366, 368) respectively comprising mappings between digital text entries (370,374,378) and probe analog writing (372,376,380), mappings between digital text entries (382,386,390) and photos of probe facial expressions (384,388,392), and mappings between digital text entries (394, 398) and probe voice data (396,398); receiving a digital search term through a graphical user interface of a type common to each of the analog writing mapping database, the facial expressions mapping database and the voice mapping database; using (440,442) the digital search term to search for a corresponding analog search term in one of: the analog writing mapping database, the facial expressions mapping database and the voice mapping database; when the digital search term matches a digital text entry in the one of the mapping databases (364, 366, 368), obtaining the analog search term corresponding to the digital search term, the analog search term comprising a probe analog writing, a photograph of a probe facial expression or a probe voice data mapping to the digital text entry matched by the digital search term; searching, using the obtained analog search term, for a matching analog writing entry, facial expression entry or voice data entry into a corresponding one of: the analog writing database, the facial expression database and the voice database; and returning the analog writing entry, facial expression entry or voice data entry (372,388,422) matching the analog search term and a data link (410,416,424) to a location of the matching analog writing entry, facial expression entry or voice data entry within the corresponding given file as a search result (408,407,421). maintaining an analog writing database, a facial expression database and a voice database, comprising respectively analog writing entries, facial expression entries, and voice data entries, each of the entries in the analog writing database, facial expression database and voice database corresponding to an analog annotation within a given file and being stored in association with a file tag identifying a given location of the analog writing entry, facial expression entry, and voice data entry within the corresponding given file; maintaining an analog writing mapping database, a facial expressions mapping database and a voice mapping database, the analog writing, facial expressions and voice mapping databases (364, 366, 368) respectively comprising mappings between digital text entries (370,374,378) and probe analog writing (372,376,380), mappings between digital text entries (382,386,390) and photos of probe facial expressions (384,388,392), and mappings between digital text entries (394, 398) and probe voice data (396,398); receiving a digital search term through a graphical user interface of a type common to each of the analog writing mapping database, the facial expressions mapping database and the voice mapping database; using (440,442) the digital search term to search for a corresponding analog search term in one of: the analog writing mapping database, the facial expressions mapping database and the voice mapping database; when the digital search term matches a digital text entry in the one of the mapping databases (364, 366, 368), obtaining the analog search term corresponding to the digital search term, the analog search term comprising a probe analog writing, a photograph of a probe facial expression or a probe voice data mapping to the digital text entry matched by the digital search term; searching, using the obtained analog search term, for a matching analog writing entry, facial expression entry or voice data entry into a corresponding one of: the analog writing database, the facial expression database and the voice database; and returning the analog writing entry, facial expression entry or voice data entry (372,388,422) matching the analog search term and a data link (410,416,424) to a location of the matching analog writing entry, facial expression entry or voice data entry within the corresponding given file as a search result (408,407,421).
