Searching Multiple Objects

List<List<sObject>> searchResults = [
    FIND 'Riverbend' IN ALL FIELDS
    RETURNING Account(Id, Name), Contact(Id, LastName, Email), Lead(Id, Company)
];

List<Account> accounts = searchResults[0];
List<Contact> contacts = searchResults[1];
List<Lead> leads = searchResults[2];

System.debug('Found ' + accounts.size() + ' accounts, ' + contacts.size() + ' contacts, ' + leads.size() + ' leads.');

1. List<List<sObject>> searchResults = [ — this is the direct payoff from this module's first lesson.
2. FIND 'Riverbend' IN ALL FIELDS — one search text.
3. RETURNING Account(Id, Name), Contact(Id, LastName, Email), Lead(Id, Company) — three object types, in this order.
4. ]; — closes the search — a single round trip instead of three separate SOQL queries.
5. (blank line)
6. List<Account> accounts = searchResults[0]; — the first object's matches.
7. List<Contact> contacts = searchResults[1]; — the second's.
8. List<Lead> leads = searchResults[2]; — the third's.
9. (blank line)
10. System.debug('Found ' + accounts.size() + ' accounts, ' + contacts.size() + ' contacts, ' + leads.size() + ' leads.'); — reports all three counts at once.

List<List<sObject>> searchResults = [
    FIND 'Riverbend' IN NAME FIELDS
    RETURNING Account(Id, Name)
];

1. List<List<sObject>> searchResults = [ — opens the search.
2. FIND 'Riverbend' IN NAME FIELDS — IN NAME FIELDS narrows the search specifically to name-type fields (like Account.Name or Contact.LastName) — useful when you know you're searching for a name specifically, not scanning notes or descriptions too.
3. RETURNING Account(Id, Name) — the object and fields to return.
4. ]; — closes the search.

String searchTerm = 'connectivity issue';

List<List<sObject>> searchResults = [
    FIND :searchTerm IN ALL FIELDS
    RETURNING Case(Id, Subject, Status), Knowledge__kav(Id, Title)
];

1. String searchTerm = 'connectivity issue'; — the search text as an Apex variable.
2. (blank line)
3. List<List<sObject>> searchResults = [ — opens the search.
4. FIND :searchTerm IN ALL FIELDS — the :searchTerm bind variable — Module 20's bind variable syntax works in SOSL too.
5. RETURNING Case(Id, Subject, Status), Knowledge__kav(Id, Title) — both open Case records and a knowledge base article object searched at once.
6. ]; — closes the search.

A support agent's global search box searching both at once is a textbook SOSL scenario — one search box, multiple object types, exactly the shape this module exists for.
