There's always something to learn and there's always somet technology or company we don't know (yet). Of the three, you should at least could have heard of ElasticSearch: it is a general purpose search server based on Apache Lucene like its cousin Apache SOLR (maybe you know it), but with REST API, JSON support etc.. You can use it for searching stuff and one (but not the only one) scenario is logging. In this case you use some other software (like Logstash but I think there are others too) to collect logs from different sources (i.e. syslog for operating systems, ruby apps via gems, raw tcp etc..) and according to a friend of mine that uses it for this purpose it's very good for its speed, easy to use, to scale etc.. N.B. I invite anyone more expert to elaborate/correct what I've said, I've just used Apache SOLR in the past and never tried ES
