By using JQL using 1) issueFunction in hasLinks("is blocked by") or 2) issueFunction in hasLinkType(Blocks) one can get the list of issues that have this link.
And in the results the column "Links" shows the issuekey that satisfy this criteria. But the shortcoming is "Links" columns also shows issuekey that does not satisfy this criteria.
Ex: Result may show ABC-123 has "Links" ABC-345, ABC-456. But only ABC-345 is the right link that satisfies the link type = Blocks. ABC-456's link type =Depends.
How to narrow downs only those Links that meet a very specific Link Type. Ex: If I search for Link Type = Blocks, I dont want to see Links that dont meet this specific Link Type.
