Content ID Search Not working

Dear Friends,

Recently we did migration to Cloud for our Rhythmyx Server. We use the Search functionality heavily used, and it worked fine till we did the migration. However, now suddenly after the cloud migration, the search functionality by content id stopped working. Strangely, even though we are not able to search by content id, but we are able to search by other fields like title…

However, when we use the content id, the search fails and returns no records found.

Has anyone experienced any similar problems where search works with other fields but not with this content id field?

thanks

I assume you reindexed search after the cloud migration?

No we did not do that. How do you re index the search?
