    Footnote
    Novice end users were given 2 hours of training in searching a full-text magazine database (Magazine ASAP(TM)) on DIALOG. Subjects searched during 3 to 4 sessions in the presence of a trained monitor who prompted them to think aloud throughout the sessions. qualitative analysis of the transcripts and transaction logs yielded empirical information on user variables (purpose, motivation, satisfaction), uses of the database, move types, and every question users asked during the searches. The spontaneous, naturalistic questions were categorized according to affective, cognitive, and sensorimotor speech acts. Results show that most of the searches were performed for the self and were work related. The most common use of the database was to retrieve full-text articles online and to download and print them out rather than read them on screen. The majority of searches were judged satisfactory. Innovative uses included browsing for background information and obtaining contextualized sentences for language teaching. Searchers made twice as many moves to limit sets as moves to expand sets. Affective questions outnumbered cognitive and sensorimotor questions by two to one. This preponderance of affective micro-information needs during searching might be addressed by new system functions

    Abstract
    Verity Search 97 software will index and search e-mail, attachments, folders and documents on local and network disk drives. The Internet may be searched via the same front end and changes to particular documents or pages may be monitored. Documents may be viewed in their native formats including ASCII, HTML, PDF and popular word processors, with highlighted search terms. Agents may be launched into the Internet to retrieve information according to a user-specified profile. The software can index about 700 MB an hour. Describes the search technology which includes fuzzy logic and natural language. The Web version of Personal Search 97 works with Netscape Navigator or Microsoft Internet Explorer, while the Exchange version will work regardless of any attachment to an Exchange server. Search 97 Personal improves online time and access time and allows searches to be refined offline

    Abstract
    Gross et al. (2015) have demonstrated that about a quarter of hits would typically be lost to keyword searchers if contemporary academic library catalogs dropped their controlled subject headings. This paper reports on an analysis of the loss levels that would result if a bibliographic database, namely the Australian Education Index (AEI), were missing the subject descriptors and identifiers assigned by its professional indexers, employing the methodology developed by Gross and Taylor (2005), and later by Gross et al. (2015). The results indicate that AEI users would lose a similar proportion of hits per query to that experienced by library catalog users: on average, 27% of the resources found by a sample of keyword queries on the AEI database would not have been found without the subject indexing, based on the Australian Thesaurus of Education Descriptors (ATED). The paper also discusses the methodological limitations of these studies, pointing out that real-life users might still find some of the resources missed by a particular query through follow-up searches, while additional resources might also be found through iterative searching on the subject vocabulary. The paper goes on to describe a new research design, based on a before - and - after experiment, which addresses some of these limitations. It is argued that this alternative design will provide a more realistic picture of the value that professionally assigned subject indexing and controlled subject vocabularies can add to literature searching of a more scholarly and thorough kind.
