Parameters
- chatRooms
- ICollection<Uri>
The chat rooms to query.
- query
- ChatHistoryQueryOptions
The query.
- userCallback
- AsyncCallback
The method to be invoked when this asynchronous operation completes.
- state
- Object
An object to be passed back to the callback.
Returns
An IAsyncResult that references this operation.
Exceptions
query
is null.
chatRooms
collection is null or empty.

Parameters
- chatRooms
- ICollection<Uri>
The chat rooms to query.
- searchString
- String
The search string.
- exactPhrase
- Boolean
if set to true the search string is treated as an exact phrase; Otherwise, the search string is treated as a collection of words to match, and any single word match yields a message in the results.
- caseSensitive
- Boolean
if set to true treat the search as case sensitive.

Exceptions
chatRooms
collection is null or empty.
The PersistentChatEndpoint is not established.
The chat server connection is not in a valid state to send the command.
The PersistentChatEndpoint encountered an error communicating with the chat server.
