How to find out who changed the custom field?

[Alexander Urzhumtsev]

We have usual text custom field "Note". And we want to know who changed field at a certain interval via JQL.

Example JQL, that I want:

Note by MembersOf("Users") and Note changed <= -3d

Historical querying is only provided on a handful of fields (statuses for instance). https://confluence.atlassian.com/display/JIRA/Advanced+Searching#AdvancedSearching-CHANGED

AND Status WAS CHANGE FROM "Resoved" To "Closed" DURING (startOfYear(),endOfYear())

But I don't know that without writing a custom index and JQL Function you can support your own fields.
