Other Operators

V301 evaluates all queries in lower case. Further, v301 evaluates all criterion as textual strings: it does not recognize words. The effect of this is that any criterion may produce undesired results. For example, if to find all headlines on a December contract, you use the query,

/Dec

v301 evaluates the query as the textual string “dec.” If the headlines containing the words “decline,” “decimate,” “decry,” as “deception,” as well as “Dec” and “December” exist, all will be included in the working set. You can mitigate the effect of this phenomenon by using the exclamation point (!) limiter in the query.

You can recall the last working set of headlines using the double-forward slash (//) operator.

Finally, parentheses () enable you to specify order of operation.
