I was wondering if it was possible to query Solr for some index-metadata, e.g. the most frequent words in the index?
If so, how do you do this? Unfortunately I wasn't able to find anything about this.
thx for any help in advance
Have a look at the LukeRequestHandler

I would like to learn if anyone has successfully indexed GroupWise archive mail into Apache Solr/lucene?
Looking for assistance on setting up a fetch.
Thank you.
By Default, SOLR comes with clustering module i.e. carrot2
http://wiki.apache.org/solr/ClusteringComponent
Try this module and it will solve your issue.
I am wondering if there is a way to look at the inverted index of a doc in SOLR? I checked solr admin tool but couldn't find anything.
Check the LukeRequestHandler within Solr, should enable you to get the index data.
there is Luke but lately is is not being upgraded to latest lucene version, someone will recompile it soon probably.
I am currently using Apache Solr to build a search engine. The queries in Solr are of the field:value format. Now I want to use a part-of-speech tagger to separate the subject, verb and predicate and search the values in each fields. For example, if I input "Who likes Starbucks" then I need some code to give me "q=subject:*&verb=likes&object=starbucks". Is there any library that can handle this job? Thank you!
I think several people have used UIMA for this, see solr wiki
There are a number of POS taggers. Here is another StackOverflow posting about this: What is a good Java library for Parts-Of-Speech tagging?
can anyone tell me if there is a way to retrieve a list of popular searches in solr and/or solrnet?
Thanks in advance

No, Solr doesn't implement anything like that. It's entirely up to you to gather/retrieve this information.
I'm very new to Solr and I'm looking at someone else's code. I'm looking at the schema.xml and found the following:
field
dynamicfield
copyField
What is the difference between these please?
Thanks! :)

They're all thoroughly explained in the Solr wiki.
Also here's a blogpost about dynamicFields, and here's another one about copyFields, they might help.
