E-books are not searchable in the organisation views of ilspilot

[pronguen]

Describe the bug

In the organisation views of ils.test.rero.ch, the Cantook e-books are searchable (1 result):
https://ils.test.rero.ch/aoste/search/documents?q=blackout%20navarro%20babelcube&page=1&size=10

This is not the case in the RBNJ view of ilspilot (0 result):
https://ilspilot.test.rero.ch/rbnj/search/documents?q=blackout%20navarro%20babelcube&page=1&size=10

However, they can be searched from the global view of ilspilot (1 result):
https://ilspilot.test.rero.ch/global/search/documents?q=blackout%20navarro%20babelcube&page=1&size=10
