Filtering on Beginning Characters

Solved prototype user 6 years ago

is there a way to filter data based on a match of the beginning characters? The HAS filter matches anywhere in the string.

I relaize how to do predictive seacrhes. However, in the example that you provide the HAS expression is used which allows matches anywhere in the word or phrase. I am looking only to match on the beginning characters of the word or expression. So for example, let's say the data master has a town called Treemont. Using HAS if someone types in "mo" it woudl match. I only want to match on "Tr" or "Tre" or "Tree". I had previously tried using the INDEX function and added a condition to see if result was equal to zero, but that didn't work. Any other alternative would be greatly appreciated.



I have the same issue and can't figure out how to achieve this. Sorry but I don't get your explanation, can you please detail it a bit further ?

My issue is:

In my data master I have a list of securities, let's say with the following values:

  • Alpine Select AG
  • General electric
  • Nestle AG

If I use the expression detailed in the tutorial, with the "HAS" filter, when I search the string "ne", I will get the 3 results. Actually, what I would like to get is only the third one, "Nestle AG", because it is the only one which begins with "ne". How can I achieve this ?

Thanks in advance for your help.


Here's how to do this:

Create an "On Key Up" + "Set Value" event on the Input Text field, having it set the value to the Data List. For the value, click calculated and enter in this expression:1b3f2cfb3198df7b114222ce3bd70ffe

This works by filtering the Data Master, using a substring to take as many characters from the row values as characters the input has, and checking which values match the values in the Data Master 'Name'.


Amazing !

It works like a charm ! Thanks a lot !
