EXPAND Numbers in SELECT Statements (continued)

Qualifying EXPAND Numbers

You can qualify an E or R number with one or more Basic Index field or limit suffix code. SELECT the E or R number, followed by a slash and the suffix code(s) you want to use.

Note: In general, field suffix codes cannot be applied to E numbers from an EXPAND in an Additional Index.

• To restrict an EXPAND entry with the English-language suffix code:

You can use a database's limit suffix codes with E numbers representing either the Basic Index or an Additional Index, as well as with R numbers SELECTed from a Related Term list.

You can also apply suffix codes to a group of E or R numbers. If the OR operator is used in the SELECT statement, the group of numbers must be placed in parentheses, with the suffix code(s) following. If a hyphen, comma, or colon is used in place of OR, no parentheses are necessary.

• To apply Basic Index and limit suffix codes to a group of R numbers:

?expand (diplomacy)

Ref   Items Type  RT  Index-term
R1      581        2 *DIPLOMACY
R2     1820   R   48  INTERNATIONAL RELATIONS
R3    28322   R  212  POLITICS

?select (r1 or r3)/de,eng
             203  DIPLOMACY/DE,ENG
           17131  POLITICS/DE,ENG
      S1   17312  ("DIPLOMACY" OR "POLITICS")/DE,ENG

If you SELECT a single-word entry from a Related Term list and you want your retrieval to reflect the use of the term as a Descriptor, you must apply the suffix /DF (Full Descriptor) to the R number (see Viewing Online Thesauri). The number of items shown in the resulting set for that entry will be less than the number shown in the Related Term list, as the number in the Related Term list reflects occurrences of the term in all Basic Index fields.

• To SELECT a single-word descriptor from an EXPAND:

?select r1/df
      S2     230  "DIPLOMACY"/DF
