Hi
A have a couple of questions on the search criteria in REST apis
https://devdocs.magento.com/guides/v2.3/rest/performing-searches.html
1. in, nin
It seems that I am expected to supply a list like this
a,b,c
a. Can an individual value contain leading/trailing spaces or are they not considered a part of a value?
b. Can I express a value with a comma in it?
Does Magento support an escaping syntax that can denote spaces and commas as belonging to a value as opposed to value separators?
c. What are finset and nfinset. Are the the same as in and nin?
The reason for my questions is that I am working on a product that aims to take a search criteria in a string form (sku=a OR sku=b) and convert in into query parameters for an underlying REST call to /customers/search or similar apis. It does involve inventing a little syntax of my own and I don't want to introduce a conflict with anything Magento expects.
Thank you.
