[TYPO3] Indexed Search Engine not working

[luca]

Hallo,

I have TYPO3 4.1.7 running in a local windows test environment.
I have installed Indexed Search Engine and Searchbox for Indexed Search 
Engine (macina_searchbox).

Indexing doesn't seem to work and search do produce any output.

Records
index_phash:   		0
index_words:   		0
index_rel:   		0
index_grlist:  		0
index_section: 		0
index_fulltext:		0
index_phash TYPES


How can I debug it and have the search box working?
I have put indexed in debug mode but I do not get any debug 
informations...Are there alternatives to this indexing engines?
Also I have a bounch of warning messages stating
No XCLASS inclusion code found in file "class.doublemetaphone.php"
A difference between the originally installed version and the current 
was detected!


Thank you

L
