Basic Index Searching (continued)

We have already been searching the Inspec database, File 4. To search for the term LEOS, I will type my search terms after the question mark prompt, limiting LEOS to the identifier field using the suffix /id and the descriptor field using the suffix /de:

     s low(w)earth(w)orbin or leos or leo
     s s1/id,de and iridium

If search terms appear in the identifier field, it usually means that these are relatively new terms being used as indexing terms in the database. It is also likely that articles will focus on that topic.

?s low(w)earth(w)orbit or (leos or leo)
          452275  LOW
           69452  EARTH  (January 1969)
           26113  ORBIT
            1376  LOW(W)EARTH(W)ORBIT
              83  LEOS
            1772  LEO
      S1    2604  LOW(W)EARTH(W)ORBIT OR LEOS OR LEO

?s s1/id,de and iridium
            2141  S1/ID,DE
            2379  IRIDIUM  (January 1969)
      S2      54  S1/ID,DE AND IRIDIUM

I'll choose the Format K and combine it with Format 6 (titles) to get a little more information than just a title list.

I think I'll print out all of these records and send them to Brian. He can decide how many he wants as complete abstracts.

Just from the excerpts we can tell that a researcher named Fantacci has corroborated in writing many of the articles on technology used in the Iridium program.

Browse the list below and then go to the next page to complete the Exercises.
