Is it possible to subquery using SOSL?

Question

I have a SOSL query that finds Salesforce Campaigns, and that's working just fine. However, I need to retrieve all Account Team Members for each returned Campaign. Is it possible to add a subquery to SOSL?

Here's what I have so far:

List<List<sObject>> searchList = 

    [FIND :CampaignSearchTerm RETURNING Campaign (Id Where IsActive = true Order By Name)];

If it is not possible, I have a different question. Can SOSL results be assigned to a Map or Set to avoid from having to put together all of the IDs in a for-loop for an SOQL query (for the sake of efficiency)?

Thanks!

Answer 1

In terms of efficiency, SOSL is only bringing <= 200 results so producing Id lists for SOQL should have a negligible impact.
