Here I'm listing relevant links from the slide-deck which are good starting point for Solr deployment.
Apache Solr Reference Guide / Wiki - Use this for main reference, for some reson all Google links go to obsolete Solr Wiki.
Points of interest in the reference guide:
Language analysis - Guides for Solr configuration for different languages
Filter reference guide - List of all Lucene filters available in Solr with descriptions
Character filter reference guide - List of all Lucene filters working on character level (e.g. ščž -> scz collapse, punctuation removal, etc.)
Basic Solr Home - a minimal Solr home configuration with two cores configured for slovene and english language
NewsBuddy - an opensource full-text search site for news articles. It has a nice example of how to effectively configure Solr for Slovenian articles.
LemmaGen Slovenian lemmatizer - Solr plugin for slovenian lemmatization
Solr Client Libraries - List of Solr client libraries
PySolarized - My Solr/Python communication library with multilanguage support
