[ https://issues.jboss.org/browse/TEIID-4992?page=com.atlassian.jira.plugin... ] Steven Hawkins commented on TEIID-4992: --------------------------------------- I think we need a formal definition of what is expected. Using the example from before: String[] first = new String[]{"vivek16","abcd","vivek44", "x", "xx"}; String[] second = new String[]{"vivek36","vivekkk","abcd","vivek445", "x"}; If we do something like: {code} for (float f : Arrays.asList(0.0f, 1f, 1.1f)) { System.out.println(Arrays.toString(intersectionFuzzy(first,second,f))); System.out.println(Arrays.toString(intersectionFuzzy(second,first,f))); System.out.println(Arrays.toString(minusFuzzy(first,second,f))); System.out.println(Arrays.toString(minusFuzzy(second,first,f))); System.out.println(Arrays.toString(unionFuzzy(first,second,f))); System.out.println(Arrays.toString(unionFuzzy(second,first,f))); } {code} We see the output: {code} [abcd, x, xx] [abcd, vivekkk, x] [] [] [abcd] [abcd] [abcd, xx] [abcd, x] [vivek16, vivek44] [vivek36, vivek445, vivekkk] [abcd, vivek16, vivek36, vivek44, vivek445, vivekkk, x] [abcd, vivek16, vivek36, vivek44, vivek445, vivekkk, x] [abcd, x] [abcd, x] [vivek16, vivek44, xx] [vivek36, vivek445, vivekkk] [abcd, vivek16, vivek36, vivek44, vivek445, vivekkk, x, xx] [abcd, vivek16, vivek36, vivek44, vivek445, vivekkk, x, xx] {code} Some things that may need clarifying are: intersectionFuzzy(first,second,0.0f) - does not contain any vivek entry, but it does when the arguments are reversed. intersectionFuzzy(first,second,0.0f) - with the arguments in either order contain more results than the similar unionFuzzy intersectionFuzzy(first,second,1.0f) - has asymmetric results depending on the order of the inputs -- This message was sent by Atlassian JIRA (v7.5.0#75005)
