Graphics QUEST3D Procedure

Select *YEAR from the NUMERIC sub-menu and respond to the standard numeric prompts.

Basic QUEST Procedure

Normally a literature search will involve tests using several of the related keywords.

Ex. Find the structure published in Acta Cryst.,C (Cr.Str.Comm.), volume 41, page 783, year 1985.

T1  *CODE  .EQ.  591
T2  *VOLU  '^41'  where ^ is blank
T3  *PAGE  '^783'
T4  *YEAR  .EQ.  1985
QUES  T1  .AND.  T4  .AND.  T2  .AND.  T3

It is good practice to enclose the volume and page values within ' marks and to leave a blank space ahead of the leading character. Since these fields are right-adjusted this ensures no irrelevant hits. Thus '^783' will hit only for page 783 and not for page 1783.

Numeric tests are executed faster than text tests; hence the order of tests in the above search question.

Note also that a given publication may contain more than one crystal structure so the first hit is not necessarily the entry which is being sought.
