Webcomponents demo for search and results - results not filtered

[LHBruneton-C2C]

Describe the bug

The results on the search and results webcomponents demo page are not filtered based on the user input.

Expected behaviour

When a user types and validates from the search bar, the results should be filtered too.

Steps To Reproduce

• Visit the demo page for the search and results webcomponents:
  https://geonetwork.github.io/geonetwork-ui/main/demo/webcomponents/gn-search-input-and-results.sample.html
• Type a search, for example "eau"
• Check that autocomplete suggestions are displayed
• Click on the search icon / Press enter
• See that the results are not changing based on the new filter

Working on d9b2a06 (from #322)
Not working on v2.6.0, v2.5.0, v2.4.0, v2.3.0.

What is the expected behavior when interacting with these components?
Should pressing Enter or clicking the search button refresh the results or trigger an external catalogue search?
Is the interaction meant to differ between text input and selecting a suggestion?
Clarifying this would help ensure proper integration into a CMS or other websites.

Hi @maxcollombin,
Thanks for taking an interest into this issue.

The combination of search and results webcomponents should have the same behavior as the components inside the Datahub.

So, if you follow the same steps, for example on https://dev.geo2france.fr/datahub/search, you can see that:

• Click on the search icon / Press enter => will change the results list based on the new filter
• Select a suggestion => will open the suggestion
