The MS Indexing Service considers certain words as "Noise" and refuses to use them for indexing, because they are being used so often. That's OK for words like "I", "a", "to" and so on. But unfortunately combinations of multiple words including one of those "noise" words are not found, too. If you're for example searching for "going to New York", MAP will search for "going AND to AND new AND york". MAP will find no email, because query includes the "noise" word "to".

To change this behaviour, you can simply empty the list of "noise words". First open the file noise.xxx which is stored in the folder /System32 in your Windows directory. The xxx is a code for the language of your Windows system. On a computer with the english version of MS Windows installed, replace the xxx with "eng".

Open the file, delete the content, save the file and close it.

To update the existing index, you have to delete the docs-directory from your index catalog and to re-create it:
Open the "Computer Management" console by navigating to Settings/Control Panel/Administrative Tools/Computer Management. Then open the "Services And Applications" branch and click on "Indexing Service" and then on "MailArchivePro". Open "Directories". Note the path. Delete the directory, then add the directory again.

By the way: using the standard noise.xxx-file we had an archive containing 40,000 emails with a size of 46 MB. After deleting all words from the noise.xxx file the new index size has been 49 MB. Nothing to worry about!
