Access is denied.  Verify that either the Default Content Access Account has access to this repository, or add a crawl rule to crawl this repository. If the repository being crawled is a SharePoint repository, verify that the account you are using has “Full Read” permissions on the SharePoint Web Application being crawled.

2. 确保Web服务器上面没有回环，可以用以下命令禁用回环

New-ItemProperty HKLM:\System\CurrentControlSet\Control\Lsa -Name “DisableLoopbackCheck” -Value “1″ -PropertyType dword

可以运行以下命令修改限制：

$ssa = Get-SPEnterpriseSearchServiceApplication
$mp = Get-SPEnterpriseSearchMetadataManagedProperty -SearchApplication $ssa -Identity "PublishingPageContentOWSHTML"
$mp.MaxCharactersInPropertyStoreForRetrieval = 2097152
$mp.Update()
