Error returned from JQL query is misleading

Problem Definition

1. go to issue search
2. switch to advanced search mode
3. type project = TEST AND status = "new"
4. I got the same errors:

• jqlTooComplex from QueryComponent!Jql.jspa
• The value 'new' does not exist for the field 'status'. from rest/issueNav/1/issueTable

where "new" status is non-existed status, when I type/select the status which exists then there's no error.

so why throwing jqlTooComplex exception even though is not complex?

Look at the following code from jira-issue-nav-components/src/main/java/com/atlassian/jira/components/query/DefaultSearcherService.java (issue-navplugin 6.4.28):

// Is the query too complex to be expressed with searchers?
        final Query query = parseResult.getQuery();
        if (!searchService.doesQueryFitFilterForm(user, query))
        {
            return ServiceOutcomeImpl.error(JQL_TOO_COMPLEX_ERROR_MESSAGE);
        }

So every time the query "does not fit filter form" the "too complex" message is returned. IMO quite misleading error, because it has nothing common with too complex but rather incorrect values were used.

Suggested Solution

Add a validation to display the right exception.
