: I am writing a custom analyzer for my field type. This analyzer would need : to use SolrResourceLoader and SolrConfig, so I want to make it : SolrCoreAware.
1) Solr's support for using Analyzer instances is mainly just to make it easy for people who already have existing ANalyzer impls that they want to use -- if you're writing something new, i would suggest implementing the TokenizerFactory API. 2) Do you really need access to the SolrCore, or do you just need access to the SolrResourceLoader? Because there is also the ResourceLoaderAware API. If you take a look at StopFilterFactory you can see an example of how it's used. FWIW: The reasons Solr doesn't support SolrCoreAware Analysis related plugins (TokenizerFactory and TokenFilterFactory) are: a. it kept the initalization a lot simpler. currently SOlrCore knows about the INdexSchema, but the IndexSchema doesnt' know anythng about the SolrCore. b. it allows for more reuse of the schema related code independent of the rest of Solr (there was talk at one point of promoting all of the IndexSchema/FieldType/Token*Factory code into a Lucene-Java contrib but so far no one has steped up to work out the refactoring) -Hoss
