No stats yet, I have not had it long.
Doesn't appear in a dictonary I have found yet, but it certainly is a term used.
It appears that it relates to Chemistry/Biology.
I have found schools that have classes called Chemology on the web, and I also just found that there is a Ministry of Chemology that apparently has awarded the following site an award. If an offical government agency uses the term in its name, this is clearly a term that does have a meaning, although I haven't found a dictonary yet with it.

Maybe this is a industry specific term, or one so new it hasn't made it into the dictonary yet. The site above seems to assign this word a meaning of the study of chemical/biology.
Here is a meaning the word is given from this site, section 260:

Let us call
the science of the kinds of matter by the name of chemology. This science will have to describe all the special properties of all kinds of matter, and among these properties, will have to describe the shapes into which matter of different kinds grows. So, then, we may reckon crystallography as a branch of chemology.
Here a site of the US government uses the term:

Other sites link this word to Biotechnology companies.
I think this domain would be best suited to serve the chemical, biology, biotechnology industry. I even found company's with this word in their name.
