I have a team-managed JIRA project that has a custom field named "Part Number". This field contains values with dashes. When I search using the queries below only a small portion show in the results. Sometimes when I run it, it shows all results. I rerun the exact same query and half the results disappear again.
"Part Number[Short text]" ~ "200-00126"
"Part Number[Short text]" ~ "\"200-00126\""
