Conducting a Subject Search (continued)

Step 4: Use Logical Operators to link concepts

We used logical operators in Lesson 4 to connect a search for patent assignee and patent dates. We will use them again in this search to connect the different sets of concepts.

Now, I will put the entire search together.

At the question mark prompt, I will type in my BEGIN command: b 340 and press the ENTER key to start the search.

The results of the BEGIN command are shown below.

?b 340

File 340:CLAIMS(R)/US Patent  1950-99/Jun 01
       (c) 1999 IFI/Plenum Data Corp
*File 340: Price increase effective June 1, 1999.  
U.S. Provisional Applications now searchable. See 
HELP NEWS 340 for more information.
 
      Set  Items  Description
      ---  -----  -----------

Next, I enter the Dialog command SELECT command at the question mark prompt followed by my search terms under Concept 1. I will conduct several searches, entering each concept group as a separate search statement.

?s video? or televi? or tv or t(w)v
           38136  VIDEO?
           19908  TELEVI?
            3849  TV
           66981  T
           84493  V
             529  T(W)V
      S1   51775  VIDEO? OR TELEVI? OR TV OR T(W)V

I will now enter the second concept group at the question mark prompt and press ENTER:

s game? or entertain? or amus? or play?

?s game? or entertain? or amus? or play?
           14496  GAME?
            1235  ENTERTAIN?

           36453  PLAY?
      S2   44744  GAME? OR ENTERTAIN? OR AMUS? OR PLAY?

I will continue to refine the search by adding the third concept at the question mark prompt and pressing ENTER.

?s aircraft? or airplane? or flight or inflight or in(w)flight or fly?
