Unable to find some articles.

[skanskan]

I don't know why I'm unable to find many articles if I use the embedded search tool on Jabref.

For example I've tried searching: Statistical Issues in Modeling Chronic Disease in Cohort Studies both with the Pubmed and Google Scholar search options, but nothing is found.

But if I go to Google scholar web site I can find it without problem.

https://scholar.google.es/scholar?hl=es&as_sdt=0%2C5&q=Statistical+Issues+in+Modeling+Chronic+Disease+in+Cohort+Studies&btnG=

What's going on?

I'm using JabRef 5.0-dev--snapshot--2018-11-20--master--614d83cea Windows 10 10.0 amd64 Java 1.8.0_191

Another example No search engine in Jabref is able to find Markov 1906 "Extension of the law of large numbers to dependent quantities"

The first occurrency here: https://scholar.google.es/scholar?q=markov+1906&hl=es&as_sdt=0%2C5&as_ylo=1905&as_yhi=1910

Google scholar doesn't allow me to export the cite. But you can find it on other sites such as http://www.citeulike.org/user/JCMartinez-Ovando/article/2969931

Hi, this works for me. Maybe you tried too many times and Google search is blocked aftwerwards. We cannot do anything about that.

Just tried again. Works for Google scholar except for the early 403 that blocks the search due to bot detection.
