    Hi @sns ,

    Does this issue happen to all users? Does this issue still happen if you use some other query ?

    1.Please check search setting allow this site or document to appear in search results.
    Site level: Settings > Site information > View all site settings > Search and offline availability > Allow this site to appear in search results
    Library level: Settings > library settings > Advanced settings > Allow items from this document library to appear in search results

    2.Please check whether this search results web part has Hit-highlighted managed properties disappear in search schema.

    For Reference: SharePoint unfamiliar error on kw search: SubstrateSearchException: Remote executors failed
