How can I add a field option in the Serach part. Can't see it although it e informs , fields.

[Vera Valshonok]

When I am in basic search, adding criteria and in this criterion i have a choice of options to choose from (fields that I usually choose in the other place in jira). One of such multichoice is missing. It exists in fields part and in the excitant form though, How can i add it to existent search?

Where can see multiple choices option of the fields in Jira (all choices there are set for a multiselect field)
