   CREATED BY: Vadim Melamed, EMAIL: vpasmodule@gmail.com
.DESCRIPTION
   USE THIS FUNCTION TO RETRIEVE POLICIES FROM DPA VIA SEARCH QUERY
.LINK
   https://vpasmodule.com/commands/Get-VPASDPAPolicies
.PARAMETER token
   HashTable of data containing various pieces of login information (PVWA, LoginToken, HeaderType, etc).
   If -token is not passed, function will use last known hashtable generated by New-VPASToken
.PARAMETER SearchQuery
   Search string to find target resource
.PARAMETER InputParameters
   HashTable of values containing the parameters required to make the API call
.EXAMPLE
   $TargetPolicies = Get-VPASDPAPolicies -SearchQuery {SEARCH QUERY VALUE}
.EXAMPLE
   $InputParameters = @{
        SearchQuery = "Vman Access Policy"
   }
   $TargetPolicies = Get-VPASDPAPolicies -InputParameters $InputParameters
