In order to achieve a good quality/price ratio the online searcher must concentrate on both the strategic approach--database selection, understanding of search software, and efficient search strategy--and the conceptual approach--analyzing semantic content. The online search expert becomes more skilled (the "Matthew" effect) while the…

Discusses the need for computer assisted strategies to search multiple databases. A method is presented in which a pool of predefined searches is set up and a strategy is developed to identify an optimal search path. The application of this method is illustrated using a search carried out in seven databases. (11 references) (CLB)

Defines corporate family searching as the act of using computerized databases to identify a parent company and all of its related companies. Business databases available on Dialog that can be searched to trace a corporate family are identified and appropriate search strategies are described. (CLB)

Sixteen queries, performed on the two systems, resulted in 247 unique relevant references from EMCS and 559 from TOXLINE. The overlap varied considerably, from 6 to 50 percent. It is remarkable that TOXLINE, with nine subfiles specially compiled for toxicology, can be supplemented by EMCS, which in the present study delivered 31 percent of all the…

Analyzed data gathered from 78 online searchers to examine attitudes toward the use of DIALOG and SDC's ORBIT command languages. It was found that most users preferred DIALOG for ease of use. Twenty sources are listed. (FM)

Concentrates on the practical, everyday aspects of online search strategy, specifically offering ideas and comments on search strategies for STAIRS users. Included are tables listing the logical operators available on the system and the search level (document, paragraph, sentence, word) of each. (Author/JD)

Describes the "Toronto Globe and Mail" database-the first example of the entire text of a major daily newspaper online, and notes the file elements and possible search strategies. (RAA)

The prototype AID system for search strategy formulation currently operational on TOXLINE is described. Utilizing a compressed in-core hash table, it relies on statistical frequency distribution information about term occurrence in a set of document texts retrieved in response to a Boolean search query, and the occurrence frequencies of the same…

Discusses the rationale, principles, required tools, advantages, and disadvantages of the Multifile Multidisciplinary (Horizontal) Search approach to searching online databases. It is noted that this approach is characterized by the use of a large number of files spanning a wide variety of disciplines. (12 references) (MES)

Describes the compilation of a quick reference chart of the main searching and printing commands and support features for the following command languages--Basis, Bibliographic Retrieval Service, Dialog, Elhill, Eurolanguage, Grips/Dirs, Orbit, Quest, Questel. Differences between command languages are discussed and a copy of the chart is appended.…

Reports a preliminary investigation into the man-machine interaction aspects of online searching, including the methodology developed for observing and recording man-machine interface in the use of online information retrieval systems. Three references are cited, and a bibliography lists 16 sources. (FM)

Five groups of searchers each performed searches using ONTAP ERIC to identify behaviors that differentiate among degrees of experience, and between searches of familiar and unfamiliar databases. Results showed that, compared to the experienced subjects, novices performed surprisingly well. Eight references are listed. (Author/SW)

Discusses methods for designing search strategies for maximum recall, including minimizing the number of concepts intersected, isolating key subtopics, adapting the strategy to the database, and minimizing problems with search words and codes. (Author/RAA)

Explains search commands for SERIDU, an online bibliographic search system developed at Brussels Free University. These commands and output formats are compared with Euronet commands (from which they were derived), with existing INFODOC storage system commands, and with the planned BIDULE system commands. An evaluation of SERIDU is included. (SW)

This paper discusses examples of searching vocabularies, i.e., lists of terms which have been prepared with the online searcher, rather than the indexer, in mind. These lists are categorized as: enhanced thesauri or subject heading lists, synonym listings, index term listings, and merged vocabularies. Eight references are provided. (EJS)
