Subject Re: Trending topics?

Thanks for your response.

I'd like to put an arbitrary set of text into Solr and then have Solr tell
me the ten most popular "topics" that are in there.  For example, if I put
in 100 paragraphs of text about sports, I would like to retrieve topics
like "swimming, basketball, tennis" if the three most popular and discussed
topics are those inside the text.

Is Solr the correct tool to do something like this?  Or, is this too
unstructured to get this kind of result without manually categorizing it?

Is the correct term for this faceting?  It seems to me that faceting
requires putting the data into a more structured format (for example,
telling the index that this is the "manufacturer", etc.)

Basically, I would like to get something like a tag cloud (relevant topics
with weights for each term) without asking users to tag things manually.
