Filter condition using a multi concatenated string

Hi,
We have a multiconcatenated string in the publishable document,which is seperated by a delimiter |. Now in a trigger,i want to filter this multi concatenated string for the first and fourth strings. How can i do it.

Hi
I am curious to know how you have created the filter to check the first and fourth substrings in a concatenated string. Please let me know.

Thanks

Hi leela,
"i want to filter " means, do you want to remove that field or do you want to create a filter based on this string? Can you provide us more details.
Thanks,
Jay

Leela,

Can you please elaborate on your string format?and what is your current process via trigger (pub/sub)

HTH,

I think you have to apply some filter conditions on the first and fourth string.We can’t implement any business logic in filter codition.It is better to implement it in the flow service
