Comparing Two List Efficiently

Unknown

What is a quick way of comparing two lists in order to find the matches? For instance, if I want to compare a list of strings with another list, what is the most efficient way to do so?

We have a few different ways of doing this. The first way is to use a For Each step and using the inbuilt String Is in List step to compare each item of List A to List B and output the matches. Attached below is an example setup of how you might want to perform this.

Secondly, we are able to do this by using a Rule Collection Filter and it will automatically sort the results. Within the attached screenshot, I have provided an example of a setup that works. You can find more documentation about Rule Collection Filters here: https://documentation.decisions.com/docs/rule-collection-filter-step
