Searching for awards containing opensearch-illegal characters fails

[mesemus]

Package version (if known): RDM13

Describe the bug

Awards search uses the q= search parameter on the background which expects a valid opensearch query string. If user wants to search, for example, by a number abcdef/ghi, the search will fail on 500. A workaround is to enclose the string in quotes "abcdef/ghi".

The preferred solution would be to use the suggest api that does the escaping automatically and works in this case.

Steps to Reproduce

1. Go to deposition page
2. Click on Add award
3. Fill in number with slashes
4. See error

Expected behavior

Should find the award.
