Need help with Script runner query

[Naveen]

issueFunction in issueFieldMatch("category = \"Nspire\"", AccuWorkChangePackage, "^. S+.") AND resolutiondate > "2017/12/31" AND resolutiondate < "2018/04/01" AND resolution changed to "Fixed Directly" by membersOf(jira-swdev-all) AND issuetype in (bug, story, task)

I want to know what do above query do?

I am new to this plugin, please explain me the below part
issueFunction in issueFieldMatch("category = \"Nspire\"", AccuWorkChangePackage, "^. S+.")

It selects all issues from a project with the Nspire category and the AccuWorkChangePackage custom field begins with any symbol followed by space and then followed by S and then followed by a symbol or a group of symblols.

It means that the value of the AccuWorkChangePackage custom field must be

<any symbol> S<any symbol or symbols>

Hello Matveev,

Thanks for the quick response, attached is the screen shot which shows the value of the ChangePackage, how can i correlate that with what you explained.(<any symbol> S<any symbol or symbols> )

I am not sure how your screenshot relates to your question.
