Why is my published article seemingly not indexed by Google or Google Scholar? I am a Masters student, in the Faculty of Science in Canada. I have a question to ask regarding literature review. I am doing a bit of studying to find protocols for my experiment (where I hope to conjugate a certain linker to a nucleic acid). I tried looking for papers with different keyword searches on Google Scholar, as well as the WebOfScience.
There could be different possibilities here - either there are no papers that have been published, or the Search Spider was not able to find the papers (which is a False Result).
I therefore tried looking for a paper which we had published 4-5 years back in Journal of Chemical and Pharmaceutical Research. It does not show up in the search results, probably because it does not have enough citations (you can try by searching this paper on Google standard search, and on Google Scholar: Potential inhibitors against acetylcholinesterase and glutathione S-transferase associated with Alzheimer's disease).
Doesn't this give false hope to certain researchers, that the work they are currently doing is novel; or make it difficult for other researchers who are trying to find a protocol to adopt?
Hoping to get some insight from the community.
Although you asked a generic question, the answer is very particular to your own particular article. Most likely, @HoboSci, got the correct answer: you published in a journal of questionable ethical editorial policy that Google Scholar refuses to index. That is, "Journal of Chemical and Pharmaceutical Research" is probably such a journal (see https://bradleymonk.com/Beall%27s_List_of_Questionable_Journals).

I looked up the issue where your own article is published: JOCPR Volume 6 Issue 3: http://www.jocpr.com/archive/jocpr-volume-6-issue-3-year-2014.html. I searched Google Scholar for your article "Potential inhibitors against acetylcholinesterase and glutathione S-transferase associated with alzheimer's disease". I also searched for a couple other articles in that same special issue and none of them showed up in Google Scholar.

Unfortunately, I don't think there's anything you can do about it because once you've published in a journal like that, you can't republish the same article anywhere else. So,the lesson is to only publish your work in reputable journals, or else your published work might become almost invisible on the Web. :-(
