Background

Welcome to the first module of the training orientated, search filter examples on OvidGO! Focused Searches. This Focused Search is a single command, single line search whose task it is to display all the records in the database you have selected. A simple, powerful and empowering search, it will enable you to narrow your focus and burrow down into the constituent parts of the database you are looking at, as well as cast spotlights on its detail. Or alternatively, you could widen your focus and draw back, to compare the relative sizes of a combination of databases you are considering to use.

The ‘docz.dz’ Command
Entered at the command line in any of Ovid MEDLINE’s search modes, the docz.dz command will search for, and display, the number of records in the resource at that particular moment in time. The docz.dz command can be used on any database on Ovid as well as on combinations of databases. In the graphic below, for instance, the command was used to establish the total number of database records in a selection of user-defined resource categories.

 

 

The table below indicates the exact number of records retrieved on the day and time of investigation.

Practice Suggestions

  1. Logon to Ovid, select Ovid MEDLINE <1946 to Present> as your database resource and enter ‘docz.dz’ at the Basic Search or Advanced Search command line. Display the first reference. When was it published? What type of document is it? For example, an article, an editorial, or a conference abstract? How can you tell?
  2. Use the Go to result option to locate and display the very last reference. When was this reference published? What type of document is it? Does it have an abstract? Does the previous reference to it have an abstract?
  3. Use ‘docz.dz’ to establish the number of records in the other Ovid databases your institution has subscribed to, for example, Embase on Ovid, APA PsycInfo, Cochrane Database of Systematic Reviews (CDSR), Cochrane Central Register of Controlled Trials (CENTRAL), KSR Evidence etc.
