#Routine Starts Here
if ((Get-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue) -eq $null) 
{
    Add-PSSnapin "Microsoft.SharePoint.PowerShell"
}


$hostA = Get-SPEnterpriseSearchServiceInstance -Identity "APP1-SPS2013"
$hostB = Get-SPEnterpriseSearchServiceInstance -Identity "APP2-SPS2013"
Start-SPEnterpriseSearchServiceInstance -Identity $hostA
Start-SPEnterpriseSearchServiceInstance -Identity $hostB

#Wait until all the search service instances are running
#Commands below should return "Online" for both servers.
Get-SPEnterpriseSearchServiceInstance -Identity $hostA
Get-SPEnterpriseSearchServiceInstance -Identity $hostB


$ssa = Get-SPEnterpriseSearchServiceApplication
$newTopology = New-SPEnterpriseSearchTopology -SearchApplication $ssa

#Topology:
#APP1: AdminComponent, CrawlComponent, ContentProcessingComponent,AnalyticsProcessingComponent
#APP2: QueryProcessingComponent, IndexComponent
New-SPEnterpriseSearchAdminComponent -SearchTopology $newTopology -SearchServiceInstance $hostA
New-SPEnterpriseSearchCrawlComponent -SearchTopology $newTopology -SearchServiceInstance $hostA
New-SPEnterpriseSearchContentProcessingComponent -SearchTopology $newTopology -SearchServiceInstance $hostA
New-SPEnterpriseSearchAnalyticsProcessingComponent -SearchTopology $newTopology -SearchServiceInstance $hostA
New-SPEnterpriseSearchQueryProcessingComponent -SearchTopology $newTopology -SearchServiceInstance $hostB
New-SPEnterpriseSearchIndexComponent -SearchTopology $newTopology -SearchServiceInstance $hostB -IndexPartition 0

#To prevent error message "Topology activation failed. Each partition must have at least one index component..."
#"...from the previous topology in the new topology.",
#You may need to reset index in your test environment before you move on.

#Activate the new search topology
Set-SPEnterpriseSearchTopology -Identity $newTopology

#Verify that the new search topology is active, and get the old topology's ID
Get-SPEnterpriseSearchTopology -SearchApplication $ssa

#Remove the old topology object. Replace the ID with your own
$oldTopology = Get-SPEnterpriseSearchTopology -SearchApplication $ssa -Identity 35ef8906-b5f2-48bf-a3e5-8b53bdcb69ea
Remove-SPEnterpriseSearchTopology -Identity $oldTopology

#Verify that all components of the new search topology are running correctly
Get-SPEnterpriseSearchStatus -SearchApplication $ssa -Text 

运行结果

2013-08-26 更新 运行完脚本后, 可能会发现有些component(比如Index component需要拷贝索引, Admin component需要一些额外的配置)的状态是黄色的三角叹号, 不用担心, 等一下就会变为正常的绿色小勾了.

如果长时间保持黄色的叹号图标, 请检查你的index分区是否还有足够空间. 如果还不行, 就得查看SharePoint 日志排错了.
