Alias parts are indexed per object, not as full paths. When an alias part was used by multiple objects, the servlet resolved the entry point by taking the first Solr hit. For example /publikationen/jahresbericht could resolve to the child qfiab/105-2025/jahresbericht instead of the standalone object with the same alias.

Changes

• Root check for the first path segment: hits that are linked via host or series to a parent with an alias are skipped, since they are reachable via the alias path of their parent.
  • If no root remains but there is exactly one hit, it is still used, so short alias urls to unique children keep working.
  • Multiple roots are logged as error and resolved deterministically by id.
• Child lookup only follows host and series: the servlet now searches children via mods.relatedItem.host / mods.relatedItem.series instead of mods.relatedItem.

No schema change and no reindex required, only already indexed fields are used.
