Some time ago we wrote a post about SOLR and Liferay. In that moment, we saw quite interesting the idea of using an external server for the indices when dealing with high availability systems. We checked that the official version only worked for specific versions of SOLR and Liferay. There exists an official version of the web plugin for SOLR 1.4 and Liferay 5.2.0 , that fails when used with Liferay 5.2.3 SE. So, we made some minor changes on the web plugin source for Liferay 5.2.3 SE (Community) and SOLR 1.4.1. Some technical details are given here:
With these minor changes, the portal uses the SOLR server indices and no errors are logged related to indexing nor searching. It is important to remark that it is not fully tested. Here is a download link to the modified version of the web plugin.
