What is the use of facets property in lucene oak index?

I have a custom Lucene index created for my project with all the required properties. This is an assets implementation project and hence the search filters are used to search assets.

This search is OOB, with custom properties added in search facets. This search is not working because of node traversal issues. The page will just show the loading icon, if we search something in the custom properties. These properties which is being searched are already indexed in the custom index and the query is picking the correct custom index as well.

Can someone help me with any property specific to use for search filters/ facets search optimization? Is the facets node and property used for this purpose? Appreciate if someone can shed some lights.

Attaching the explain query results from query performance tool here.

Query causing issue: /jcr:root/content/dam//element(*, dam:Asset)[((fn:lower-case(jcr:content/metadata/@lcl:articleId)='20014477'))]/(rep:facet(jcr:content/metadata/dc:format)|rep:facet(jcr:content/metadata/dam:status))

 

Index definition created:

Can you try to remove the "fn:lowercase" function from your query? That should help to avoid traversals without the need to further adjust your index definitions.

Can you show the query which is executed and then also the index definitions you created/customized?

        @joerghoh  The query all comes OOB. We are using OOB search facets for the search filters and 8just added few custom properties as well in the search facets form. We have checked 'Ignore Case' property and hence the "fn:lowercase" comes in the OOB query.
