A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

PowerCmd Protocol Troubleshooting

This section describes the troubleshooting for the PowerCmd protocol.

Before starting troubleshooting with the PowerCmd protocol, make sure that the following steps are performed:

Both the Data Flow Probe machine and the remote discovery machine enabled PowerShell.
To check whether PowerShell is enabled, do the following:
1. Open the Command Prompt window.
2. Enter powershell -help. The PowerShell help information should appear. Otherwise, install PowerShell.
The Data Flow Probe machine can create PowerShell connection to the remote discovery machine.
To do so,
1. Open the Windows PowerShell window.
2. Enter enable-psremoting.
3. Type A and press Enter to continue.
4. Enter winrm g winrm/config/client. The output should be like as follows:
  Client NetworkDelayms = 5000 URLPrefix = wsman AllowUnencrypted = false Auth Basic = true Digest = true Kerberos = true Negotiate = true Certificate = true CredSSP = false DefaultPorts HTTP = 5985 HTTPS = 5986 TrustedHosts = *
  Note: * means all.
5. Enter New-pssession –computername yourservername –credential yourcredential to verify whether the connection can be created successfully.
The Data Flow Probe machine installed .Net framework 3.5.
The Data Flow Probe machine can execute all PowerShell scripts.
To do so,
1. Run gpedit.msc.
2. In the Local Group Policy Editor dialog box, go to Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Windows PowerShell > Turn on Script Execution.
3. Double-click Turn on Script Execution, and then click Enabled.
4. In the Execution Policy list, click Allow all scripts.
5. Click OK.

Problem: A remote host cannot be connected by the PowerCmd protocol.

Solution: Check if the PowerCmd connection can be made between Data Flow Probe and the target host. To do so,
1. Log in to the Data Flow Probe machine.
2. Locate the PowerCmd.ps1 file in the <DataFlowProbe_Home>\runtime\probeManager\discoveryResources directory.
3. Open the Command Prompt window in the same directory.
4. At the Command Prompt, invoke the following command:
  
  powershell .\PowerCmd.ps1 <machine name or ip> <username> <password>
5. The output should be like as follows:
  
  powershell .\PowerCmd.ps1 1.2.3.4 admin password Connecting to 1.2.3.4 MAM:Remote>hostname myremotehost1 MAM:Remote>
Problem: The PowerCmd.ps1 file in the <DataFlowProbe_Home>\runtime\probeManager\discoveryResources directory cannot be loaded because the execution of scripts is disabled on this system.

Solution: By default, the PowerShell scripts are not allowed to execute on the Data Flow Probe machine if the scripts are not signed. To enable the feature, refer to Step 4.
