AEM 6.5.13 known issue - asset move issue caused by unable to fetch content fragment references

[akashdeepAEM]

Hi,

cc @Jörg_Hoh @kautuk_sahni,

When trying to move/delete/publish either Content Fragments or Sites/Pages, there is an issue when Content Fragment references are fetched, as the background query fails; i.e. the functionality does not work.
To ensure correct operation, you must add the following properties to the index definition node /oak:index/damAssetLucene (no reindexing is required):

"tags": [
"visualSimilaritySearch"
]
"refresh": true

Clarification -

1)  Could you please confirm, the type of property is String (refresh="true") 

and not boolean (refresh="{Boolean}true").

2) with oak reindex we notice,  file doesnt exists warning. Should we complete delete the indexes and restart or we can ignore such warnings. 
*WARN* [oak-lucene-4869] org.apache.jackrabbit.oak.plugins.index.lucene.IndexCopier File _d.fdx doesn't exist in /Users/someuser/aem-author65/crx-quickstart/repository/index/damAssetLucene-1655367479986/suggestdata


Thanks,

"tags": [
"visualSimilaritySearch"
]
"refresh": true

Here tags is String[] and refresh is Boolean

Thanks, Yes found the documentation on the property types. 
"tags": [
"visualSimilaritySearch"
]
"refresh": true

https://jackrabbit.apache.org/oak/docs/query/lucene.html#stored-index-definition#refresh
tags
Optional multi value property. Defaults to empty.
List of tags of this index.

refresh
Optional boolean property.
Used to refresh the stored index definition. See Effective Index Definition

2) Just wanted to confirm, completely deleting the indexes and restarting CQ is safe and will not corrupt the instance.
