<p>The string supplied in str_ is used by <em>operator()</em> to decide whether the pair of strings supplied to it constitute a valid range. If prefix_ is true, the first value in a range must begin with str_ (and the second value may optionally begin with str_); if prefix_ is false, the second value in a range must end with str_ (and the first value may optionally end with str_).</p>
<p>If str_ is empty, the setting of prefix_ is irrelevant, and no special strings are required at the start or end of the strings defining the range.</p>
<p>The remainder of both strings defining the endpoints must be valid floating point numbers. (FIXME: define format recognised).</p>
<p>For example, if str_ is "$" and prefix_ is true, and the range processor has been added to the queryparser, the queryparser will accept "$10..50" or "$10..$50", but not "10..50" or "10..$50" as valid ranges. If str_ is "kg" and prefix_ is false, the queryparser will accept "10..50kg" or "10kg..50kg", but not "10..50" or "10kg..50" as valid ranges. </p>
