In watson conversation how to extract multiple values entered in input text

Question

Iam working on an application where I display products in my inventory based on the user's "price range"..

I need to know how to extract the values (prices) entered in the input text.

I tried using the system entities @sys-currency & @sys-number but I can extract only one value(the first value)..

example:

the user asks to "display products between $200 and $500"

how can i extract both the values to be compared with the individual products prices and display relevant products..

suggestions appreciated..

In the node in watson conversation you can access entities as array. In your case it will be:

Currency 1: <? entities['sys-currency'] != null && entities['sys-currency'].size()> 0 ? entities['sys-currency'][0].value : "---" ?>; Currency 2: <? entities['sys-currency'] != null && entities['sys-currency'].size()> 1 ? entities['sys-currency'][1].value : "---" ?>

You need to add proper null checks and checks if array has more that one entered currency
