Create search topology with PowerShell - Part 2

Article
04/24/2012

In my recent post I described the initial configuration of a search topology. This posting will show you how to configure crawl and query topologies. To do this you need to run the following steps:

Step 1: Configure administrative component
Step 2: Creating new crawl topology
Step 3: Creating new crawl database
Step 4: Creating crawl components
Step 5: Activate the crawl topology
Step 6: Cleanup crawl objects
Step 7: Creating new query topology
Step 8: Creating new property database
Step 9: Configuring index partition
Step 10: Creating query component
Step 11: Activate the query topology
Step 12: Cleanup query objects

This is how to run these steps with the appropriate PowerShell script:

$searchSA = "FARM01_ENTW_Enterprise Search"
$searchAdminCompData = "C:\MSS\SearchAdminComponent"
$searchAdminServer = "FARM01-DEV01"
$searchCrawlDBName = "FARM01_DEV08_EnterpriseSearchCrawlDB_00"
$searchCrawlDBServer = "SERVICE_ALIAS"
$allCrawlComponentServers = @("FARM01-DEV08")
$searchCrawlIndexLocation = "C:\MSS\Index"
$numIndexPartitions = 1
$searchPropertyDBName = "BTRX01_PROG08_EnterpriseSearchPropertyDB_00"
$searchPropertyDBServer = "SERVICE_ALIAS"

I've tested that script on multiple Single-Server-Installations successfully but did not find the time to fully test this on a farm deployment. So any feedback on that is highle appreciated if you run this script on a farm.
