Deep Web Searching

Wild Bill

Recommended Posts

I just ran across a search engine that searches the "deep web" which consists of websites that are not indexed by Google and the standard search engines. This particular engine is devoted specifically to scientific information only.


Scirus is the most comprehensive scientific research tool on the web. With over 575 million scientific items indexed at last count, it allows researchers to search for not only journal content but also scientists' homepages, courseware, pre-print server material, patents and institutional repository and website information.


I typed in "cannabis" and came up with these results;


Journal sources (42,958)

    ScienceDirect (22,468)
    MEDLINE / PubMed (11,996)
    Wiley-Blackwell (2,092)
    Pubmed Central (2,012)
    Springer (1,805)
    BMJ Group (700)
    BioMed Central (660)
    SAGE Publications (382)
    Nature Publishing Group (344)
    Lippincott Williams & Wilkins (131)


Preferred web (14,204)

    Patent Offices (6,574)
    NDLTD (3,331)
    Digital Archives (2,983)
    MD Consult (533)
    RePEc (480)
    DiVA (319)
    Way (136)
    PsyDok (117)
    The University of Hong Kong (93)
    University of Toronto T-Space (91)
    Organic Eprints (45)
    Humboldt (28)
    Department of Energy (26)
    MIT OpenCourseWare (12)
    Faculty1000 Posters (6)
    Cognitive Sciences e-prints archive (6)
    HKU Scholar's Hub (5)
    Curator (4)
    E-Print ArXiv (2)
    Caltech (2)

   Other web (259,222)

File types

    HTML (286,674)
    PDF (48,517)
    Word (1,802)
    PPT (932)
    PS (16)
    TeX (5)


All of these are legitimate scientific sources, none of the usual forum stuff. You can get the facts straight from the horses mouth here.


Might help with supporting documentation for new conditions.

Scirus is set to retire in early 2014. An official retirement date will be posted here as soon as it is determined.


To ensure a smooth transition, we are informing you now so that you have sufficient time to find an alternative search solution for science-specific content.


Thank you for being a devoted user of Scirus. We have enjoyed serving you.


better use it quickly.

Too bad. Here's another site that might be helpful.



OJOSE (Online JOurnal Search Engine) is a free powerful scientific search engine enabling you to make search-queries in different databases by using only 1 search field. With OJOSE you can find, download or buy scientific publications (journals, articles, research reports, books, etc.) in up to 60 different databases.


N.B. Most databases are using ENGLISH, follow this link to translate your terms into the right language

What if it's in English but I still need an translator ?? 


Here's an example:


"Taken together, we showed that AEA induces a reduction in decidual cell viability by a mechanism involving CB1 activation, which results in ceramide synthesis de novo and p38 phosphorylation, followed by mitochondrial stress and ROS production, leading to apoptosis."


So I guess I recognize a couple of those words....lol


Actually, these search engines are a great resource.  Thank you!
