> *Problem*
> The IndexDefMergerUtils uses the ancestorName and customName values for setting the merges property when merging an index instead of the latest product Index Name and custom name.
> *Example*
> Given the following indexes:
> newIndexes: [index-2]
> allIndexes: [index-1, index-1-custom-1]
> Calling IndexDefMergerUtils.merge(newIndexes, allIndexes) would result in an index with the property:
> index-2-custom-1: {
>   merges: [index-1, index-1-custom-1] 
> }
> *Result*
> When the new index-2 definition is loaded, the index-1 definition in the repository will be superseded and no longer be active. Since the [IndexName class|https://github.com/apache/jackrabbit-oak/blob/45e05adb16ce65b2867b0de48a86291a8f01720d/oak-search/src/main/java/org/apache/jackrabbit/oak/plugins/index/search/spi/query/IndexName.java#L248] will only consider an index active if every index it references in the merges property is either active, disabled or removed, the new index-2-custom-1 index will not be active and therefore not considered for queries.
> *Expected Result*
> The merged index will be created in a way that the new custom indexes are considered for queries once the merged version of the base index is active.
