What is Salesforce Object Search Language (SOSL) in Apex ?  Salesforce Object Search Language (SOSL) is a Salesforce search language that is used to perform text searches in records. Use SOSL to search fields across multiple standard and custom object records in Salesforce. SOSL is similar to Apache Lucene. SOSL statements evaluate to a list of lists of sObjects, where each list contains the search results for a particular sObject type. The result lists are always returned in the same order as they were specified in the SOSL query. If a SOSL query doesn’t return any records for a specified sObject type, the search results include an empty list for that sObject. Use the Query Editor: The Developer Console provides the Query Editor console, which enables you to run SOSL queries and view results. The Query Editor provides a quick way to inspect the database.

Asynchronous Apex in Salesforce  Asynchronous Apex is used to run processes in a separate thread, at a later time. An asynchronous process is a process or function that executes a task "in the background" without the user having to wait for the task to finish. Here’s a real-world example. Let’s say you have a list of things to accomplish before your weekly Dance Revolution practice. Your car is making a funny noise, you need a different color hair gel and you have to pick up your uniform from your mom’s house. You could take your car to the mechanic and wait until it is fixed before completing the rest of your list (synchronous processing), or you could leave it there and get your other things done, and have the shop call you when it’s fixed (asynchronous processing). If you want to be home in time to iron your spandex before practice, asynchronous processing allows you to get more stuff done in the same amount of time without the needless waiting.
