Description

Issue Summary

This is reproducible on Data Center: yes

Searching a text starting or ending with an equal sign (=) fails with an error in Confluence UI. Also, some operators like OR, AND or NOT cause the same error message.

Steps to Reproduce

Approach 1)

Access to the Quick Navigator search in the top right of your Confluence instance.
On the Search field, search by any of the following: =, =text, text=, OR, AND, NOT.

Approach 2)

Use the REST API for searching:

https://<CONFLUENCE_HOST:CONFLUENCE_PORT>/confluence/rest/api/search?cql=siteSearch%20~%20%22=%22%20AND%20type%20in%20(%22space%22,%22user%22,%22com.atlassian.confluence.extra.team-calendars:calendar-content-type%22,%22attachment%22,%22page%22,%22com.atlassian.confluence.extra.team-calendars:space-calendars-view-content-type%22,%22blogpost%22)&start=0&limit=20&excerpt=highlight&expand=space.icon&includeArchivedSpaces=false&src=next.ui.search

Expected Results

Confluence searches as text for any title that contains the equal sign.

Actual Results

When using approach 1) to reproduce the issue, the following message appears in the UI:

Something went wrong. Refresh the page, or contact your admin if this keeps happening.

When using approach 2) to reproduce the issue, the request returns a HTTP 500 error code:

{"statusCode":500,"message":"","reason":"Internal Server Error"}

Either way, the below exception is thrown in the atlassian-confluence.log file:
