Support : Dialog Search Aids : Successful Searching : Limits of the MAP Command

MAP (continued)

Limits of the MAP Command

Length of SELECT Statements

A single SELECT statement generated by the MAP command is restricted to a total of 240 characters. If the search statement exceeds 240 characters, the system will automatically create an additional SELECT statement.

Maximum Number of SELECT Statements

A SearchSave created by a MAP command will create a maximum of 50 SELECT statements. The system automatically creates a final SELECT statement that ORs together the results of the 50 sets in one combined set.

If a MAP command creates more than 50 SELECT statements, the system will automatically generate an additional SearchSave. Each of the SearchSaves must be EXECUTEd separately, and their results either used independently or ORed together. (Using OR to combine the results of separate SearchSaves will eliminate duplicate records from the final set.)

• If more than 50 SELECT statements are created by MAP, Dialog generates additional SearchSaves:

5 SearchSaves,  3024 Search Term(s) 

(File 351: Derwent World Patents Index^®)

Maximum Number of SearchSaves

The MAP command creates up to 12 complete SearchSaves. If more than four are needed to MAP a large number of records, or if the STEPS option is used to MAP more than 200 unique search terms, a 13th SearchSave is created to complete MAPping of the last record in the process when the limit was reached. Dialog will display a message warning you that the limit has been exceeded and indicating the item number of the last record to be completely processed. For complete MAPping of a large number of records, you must enter a second MAP command, specifying the item range to be processed.

• If a MAP command creates more than 12 complete SearchSaves, you must enter a second MAP command:

?s migraine and py=2007:2008
            8502  MIGRAINE
         1495008  PY=2007 : PY=2008
      S4    2706  MIGRAINE AND PY=2007:2008

Note: To extend the preceding examples, EXECUTE the SearchSaves individually, and then use OR to combine the results in a single set. EXECUTE must be used, rather than EXECUTE STEPS, to avoid exceeding the maximum number of sets (999) that can be created in any single search.
