Hi,

I am looking for a simple way (UDF?) to establish the similarity between strings. The SOUNDEX and DIFFERENCE function do not seem to do the job.

Similarity should be based on number of characters in common (order matters).

For example:

Spiruroidea sp. AM-2008

and

Spiruroidea gen. sp. AM-2008

should be recognised as similar.

Any pointers would be very much appreciated.

Thanks.

Christian
