Notes Error: Maximum allowable documents exceeded for a temporary full text index

While executing FTSearch method on NotesView class you might get an exception which says "Notes

Error: Maximum allowable documents exceeded for a temporary full text index" 

The exception occurs when Full Text indexing is disabled on the database and the number of items in the database is huge.

When we try to execute a FTSearch method on such a database a temporary Full Text index is created on the database. The number of items which can be indexed by this temporary index is set to some default value and if the number of items in the database exceeds this default value then we get this exception. We can override this setting in server's notes.ini using the following parameter 

TEMP_INDEX_MAX_DOC=number

Once we set this number to a value greater then number of items in the database the API should start working.

Accessing Lotus Notes Database from .NET

I am working on a project where i need to get some data our of Lotus Notes application and found a couple of ways to extract the data out. 


1) Easiest way to extract the data is to use Lotus Notes SDK which gets installed on the system when the Notes Client is installed. 
You can set a reference to domobj.tlb and generate a interop assembly to call the APIs. The API documentation can be found on here. 
Some of the APIs like search on the NotesDatabase doesn't seem to work and if that's the case then we can use the second approach.


2) The best part of lotus notes is that the data is exposed using ODBC. We can install the ODBC driver can be downloaded and installed from here.Once done we can use the classes from System.Data.Odbc namespace and access the items and their properties. 


Will post some tweaks when i start using these things....
