Search Platform/Weekly Updates/2025-09-22

Highlights

In collaboration with Wikidata Platform Team, we rewrote a query to load a category tree. Until now this retrieval relied on a custom layer on top of Blazgraph, so rewriting it in plain SPARQL removes another blocker for putting Blazegraph out of service. Besides that, we continue our migration from OpenSearch 1.3 to 2.19 (and ultimately 3.x).
