star (parameter with space or dash)

Hi, I have a pattern with 3 stars, pattern "* * *" template relearn();

then I can read sigle parameters by using:

var brand = sentence.get(#word, 0);
var series = sentence.get(#word, 1);
var year = sentence.get(#word, 2);

but one of the parameter can have space for example par1 par2 par 3

so the words become 4 becose a space.

I have to read 3 parameters from the 3 starts

How can I solve this situation ? 

Also if the user input 1par 2-par 3par, the second parameter is ignored I mean in #word1 I find obly 2 and not 2-par

 Thanks in advance
