Sometimes Lucene and Solr out of the box functionality is not enough. When such time comes, we need to extend what Lucene and Solr gives us and create our own plugin. In todays post I’ll try to show how to develop a custom filter and use it in Solr.
One of the new features, which will be introduces with Solr 4.0 is a new SpellChecker implementation, which doesn’t require its own index. I decided to take a quick look at it and share my thoughts.
We are proud to inform that we deployed a new version of explain.solr.pl, software for debugging and analyzing Solr queries. This version contains the following changes: bugfixes initial support for dla Solr 4.0 support for ruby 1.9 Source code is available on our GitHub.
