- To include an external object in SOSL and Salesforce searches, enable search on both the external object and the external data source.
However, syncing always overwrites the external object’s search status to match the search status of the external data source.
- Only text, text area, and long text area fields on external objects can be searched. If an external object has no searchable fields, searches on that object return no records.
- We recommend that you set up the external system to interpret the search query strings as you prefer. For example, perhaps your users want to search for case-insensitive strings.
Also review the considerations for each Salesforce Connect adapter that you use.
