We need to use these endpoints instead of the relatively unstable "/results" endpoint. We can then also add support for "more like this" MLT search.</p> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>Switch to the JSON:API endpoint, meaning we can use the DocumentFactory. Support MLT and change the request made to Vragen.ai when that tag has been set.</p> <h3 id="summary-remaining-tasks">Remaining tasks</h3> <p>None.</p> <h3 id="summary-ui-changes">User interface changes</h3> <p>Removed the search system selection.</p> <h3 id="summary-api-changes">API changes</h3> <p>Its no longer possible to choose a specific system, filtering is done via ConditionGroups.</p> <h3 id="summary-data-model-changes">Data model changes</h3> <p>Removed the default search system config key.</p>
