ySTH,

Thats really great what you just said. I was searching for such help for a while.

but there is an issue, how to make it match the expression only once. for example assuming word is:
"gogo" the ngram will be go-og-go
word requested to check is: "golo" so the gram will be go-ol-lo

The number of matches in the current code will be 2 as it counted go twice, although it should only be counted once as it should be matched only once.. so the score should be 1....

Please Help.

waiting your kind reply
Thank you very much
