Notes about indexed properties:

Queryable properties can be used in search queries (either programmatically or in KQL queries) for In-Place eDiscovery and in AQS queries by search clients such as Outlook Web App in property:value pairs, for example, from:bsuneja@cotoso.com.
Searchable properties are properties that can’t be specified in property:value pairs, but a keyword search returns the value if found in any searchable property. For example, you can’t use body:Contoso to search for the string contoso in the message body only. However, a search for that string will return all items where the property is found in any searchable property.
Retrievable properties such as documenteid and ispartiallyprocessed are returned with every search.
