We are experiencing an issue with Jira JQL text search when filtering for the value "AM".

The following JQL does not return any results, even though the value "AM" clearly exists in the issue description:
 
 
project = HM AND description ~ "AM"
At the same time, searching for other short values works as expected, for example:
 
 
{{description ~ "AA"
description ~ "PM"
description ~ "UI"}}
This indicates that the issue is specific to the value "AM".

It appears that "AM" is treated as a stop word by Jira’s text indexing and therefore cannot be searched, which makes it impossible for us to filter issues reliably when "AM" is used as a meaningful code/value in the description.

Expected behavior:
The JQL filter should return issues containing the exact value "AM" in the description.

Actual behavior:
No results are returned when searching for "AM".

Please let us know:

• whether this is expected behavior,

• if stop-word handling can be configured or overridden,

• or if there is a recommended workaround to make "AM" searchable.

Thank you for your support.
