[jira] Updated: (SOLR-1147) QueryElevationComponent : updating elevate.xml through HTTP

     [ https://issues.apache.org/jira/browse/SOLR-1147?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Nicolas Pastorino updated SOLR-1147:
------------------------------------

    Attachment: QueryElevationAdministrationRequestHandler.java

The attached RequestHandler could be a solution to the problematic presented above. Please note that the API usage may be awkward, as well as the way Java is leveraged. That's my first Solr extension :) And yes, there are quite a few unresolved things, spottable through the _'TODO'_ and _'FIXME'_ annotations.

It was tested against Solr's trunk, and seems to be working. The new Elevate configuration is to be passed, as an XML string, in the "elevate-configuration" request parameter.

> If one wants to update the configuration file for the QueryElevationComponent, direct edition of the file is mandatory. Currently the process seems to be : 
> # Replace elevate.xml in Solr's dataDir
> # Commit. It appears that when having elevate.xml in Solr's dataDir, and solely in this case, commiting triggers a reload of elevate.xml. This does not happen when elevate.xml is stored in Solr's conf dir.
> As a system using Solr, i would find handy to be able to push an updated elevate.xml file/XML through HTTP, with an automatic reload of it. This would remove the currently mandatory requirement of having a direct access to the elevate.xml file, allowing more distributed architectures. This would also increase the Query Elevation system's added value by making it dynamic, configuration-wise.
