Search crawl is running indefinitely..No documents are searchable in MOSS2007

Issue: Search crawl is running indefinitely..No documents are searchable in MOSS2007.

Root cause(s):

1)      The content access account is not updated  in all the servers.

2)      There is an issue with content  index propagation and channel between query server and index server is not responding.

Resolution:

1)      Updated farm content access account using STSADM command:

               stsadm.exe -o spsearch -farmcontentaccessaccount DomainName\UserName -farmcontentaccesspassword NewPassword

2)      Created new content  index propagation location and updated using below command.

stsadm -o osearch -propagationlocation <New propagation location>

SharePoint2010: Create Unique FileName when adding an item in document library programatically using Lambda expression.

public static string CheckFileNameIsUnique(string FileName)
{
string UniqueName = string.Empty;
try
{
SPList splCurrentList = SPContext.Current.Web.Lists["MYLIST"];
bool IsNotUnique = true;
int UniqueIndex = 0;
while (IsNotUnique)
{
UniqueIndex++;
UniqueName = FileName + "_" + String.Format("{0:000}", UniqueIndex);
var listEnumeration = splCurrentList.Items.OfType();
//If any matching record found, IsNotUnique returns "True", else returns 'False".
IsNotUnique = listEnumeration.Any(p => Convert.ToString(p["FILENAME"]).Trim() == UniqueName.Trim());
}
}
catch (Exception ex)
{
}
return UniqueName;
}

Check whether the current user exists in any SharePoint security groups

public static Boolean isUserInGroup(string groupName)
{
using (SPWeb spwebCurrentWeb = Functions.GetCurrentWeb())
{
SPGroup spGroup = spwebCurrentWeb.Groups[groupName];
if (spGroup!= null)
return spwebCurrentWeb.IsCurrentUserMemberOfGroup(spGroup.ID);
else
return false;
}
}

Copy data between SPListItems for matching fields in SharePoint.

1. Below code snippet will copy all the matching field data from spListItem2 to spListItem1 without hardcoding the field names.

SPListItem spListItem1 = spListItemCollection1[0];
SPListItem spListItem2 = spListItemCollection2[0];
SPFieldCollection spCollContentTypeFields = spListItem1.ContentType.Fields;
foreach (SPField field in spCollContentTypeFields)
{
if (spListItem2.Fields.Contains(field.Id))
{
if (string.Compare(Convert.ToString(spListItem1[field.StaticName]).Trim(), Convert.ToString(spListItem2[field.StaticName]).Trim(), true) != 0)
{
spListItem1[field.Id] = spListItem2[field.Id];
}
}
}
spListItem1.Web.AllowUnsafeUpdates = true;
spListItem1.Update();

Hope this helps, happy coding...
