Abstract
This paper considers the problem of a qualitative searches in abstract and biographic databases. It analyzes two classes of search instruments, viz., with the application of retrieval requests based on the Boolean combinations of terms and instruments that use free sentences in a natural language. It is noted that the first class of systems gives a clearer insight into the result but demands high qualifications from a user; it is very difficult to achieve high indicators of search completeness with them. The second class of systems is simpler in its workings, permits the processing of more verbose queries, and is oriented to an unqualified user. However, the output in such systems requires a longer browsing routine to search for relevant records. The experience in using an untraditional search engine with the automatic creation of terminological combinations from a query text is described. Many terminological combinations from a query text, which are contained in the documents found during a search, are issued to a user as an intermediate result. There is a convenient mechanism for browsing through the terminological combinations that are of interest to a user and through the found records themselves, as well as the mechanism for searching by subject heading indices with the output to them through a query text. Illustrative examples of using the system during searching in the abstract Medicine VINITI DB are given.
