"At the base, Solr indexes are Lucene indexes, so one can always drop down to that level."
That's what I'm looking for. I understand, that at the end, there has to be an inverse index (or rather multiple of them), holding all "words" which occurre in my documents, each "word" having a list of documents the "word" was part of. I would like to do some statistics based on this information, would like to analyze how it changes if I change my text processing settings, ... If you would give me a starting point like "Data is stored in Lucene indexes, which are documented at XXX. In a request handler you can access the indexes via YYY.", I would be perfectly happy figuring out the rest on my own. Documentation about 4.0 is a bit limited, so it's hard to find an entry point. cheers, Achim Am 11.01.2013 um 20:54 schrieb Gora Mohanty: > On 12 January 2013 01:06, Achim Domma <do...@procoders.net> wrote: >> >> Hi, >> >> I have just setup my first Solr 4.0 instance and have added about one >> million documents.
