---+ Setting OpenSearch ShortName to ease deployment of Virtuoso Faceted Browser (FCT) as search engine
---++ What
Virtuoso's Faceted Browser can be used as a search engine by any [[http://www.opensearch.org/Specifications/OpenSearch/1.1][OpenSearch]]-compliant browser.
All the user needs to do is click on the
add this engine link on the FCT page, e.g., http://linkeddata.uriburner.com/fct/, which will automatically add that Faceted Browser to their browser's list of search engines:
%BR%%BR% %BR%%BR%
The name shown in the browser's search engine menu will be the human-readable [[http://www.opensearch.org/Specifications/OpenSearch/1.1#The_.22ShortName.22_element]["ShortName"]] from the OpenSearch Description Document, automatically generated by FCT's built-in opensearchdescription.vsp.
---++ Why
Unless otherwise configured, Virtuoso will use the DefaultHost value from the [URIQA] section of the INI file as this ShortName.
However, OpenSearch dictates that this plain-text value be [[http://www.opensearch.org/Specifications/OpenSearch/1.1#The_.22ShortName.22_element][no more than 16 characters long]], which is often exceeded by the DefaultHost value (e.g., linkeddata.uriburner.com).
When the DefaultHost value is longer than 16 characters, the following warning will be presented in the Virtuoso log:
14:47:21 PL LOG: facets: ShortName from URIQA too long. Please set 'fct_opensearch_shortname' in registry
---++ How
To avoid or resolve the warning above, a command of the following form should be executed in iSQL or through the Conductor UI (http://example.com/conductor):
set registry_set ('fct_opensearch_shortname', '16 or fewer chars')
For example,
set registry_set ('fct_opensearch_shortname', 'URIBurner FCT')
