Content by label - when label has '/' character, when clicking "more" it fails to return 17 items it says are present

h3 Symptoms
Confluence 5.5
I have a page with Content by label
my label has a / character
RiskFoundation/ongoingSpecs
It shows a list of 6 items on my page
It says there are 17 more

"
Architecture Componentization
Page:
Audit Tables
Page:
Data Quality after imports BI App
Page:
How to work collaboratively on RiskFoundation Platform
Page:
List Settings
Page:
Load Results
17 related results"

It searches for this:
(labelText:riskfoundation/ongoingspecs)

when I click on the link, I get an error that there are no matches

"No results found for (labelText:riskfoundation/ongoingspecs). Please try one of the following suggestions:
Use more general search terms or consult the online documentation for tips.
If you are filtering by space, content, last modification date or contributor, try removing or adjusting the filter"

If I modify the search to just say ongoingSpecs, the search will work but then the page will not list the 6 items.

Cause

This occurs because the label macro itself can handle a label containing a "/" character, but when search is invoked it fails.

• This search fails: labelText:riskfoundation/ongoingspecs, and this is what the macro passes to search when the link is clicked.
• This search works: labelText:"riskfoundation/ongoingspecs"

Workarounds

1. The simplest is to create a new label without the backslash, and use that instead.
2. Alternatively when you click on the 'related results' link, you can wrap the label in " characters and the search will succeed.
