Manuals and Guides

  • Updating LEYES Search Resources


    In order to disseminate new Search Resources at Health Legislation Portal, we request to replace the link to LEYES database at each VHL. Previously routed to the LEYES´s iAH search interface, from now on, the link must take the user to the Health Legislation Portal homepage.



    Launched in 2011, the Health Legislation Portal brings innovations in search resources. The main novelty is the use of integrated iAHx search engine. This interface has filters (clusters) that quickly refine searches by: documents with full text, country, act type, subject, year and language. Other new feature is the inclusion of an area of outstanding issues in Health Legislation.

    The search result is filtered by country records. From the records of the country, click XML.


    Note that a page with the data in XML format appears. Just use the link on this page.


    • Copy the XML link. In the example of Argentina:

    • Copy the link with html output and replace it by old link to the LEYES database.

    About updating strategies of metasearch from VHL through iAHx

    OBS: These processes must be used only for using the LEYES database VHLs as a information source from IAH.

    The following example shows how they should be configured metasearch strategies:


    Note that this setting will do a search on all available information sources in VHL Health Legislation (Argentina, Brazil, Chile, etc). To restrict a search to a specific source, please include "where=" parameter with the information source name, for example BRAZIL, as shown in the following example:


    Disabling old search interface

    The iAH search interface will be available until November 30, 2012. For this reason, we request to exchange LEYES link until this date.
