问题
I'm new to Solr and am looking for a way to record searches (or keywords) to a log file or database so that I can then analyse for data visualisation.
- Can Solr do this already?
- Is this data accessible via. a Solr query?
Thanks.
Update 1
I'm starting to think I might need to write my own Solr analyzer?

I think it depends on what you are looking to log? Are you just looking to record the queries users are submitting as well as the results? If it's just "what are folks searching for" then you have that data in the q parameter that is logged by the servlet container. If you are using the default Jetty setup, look at ./logs/*request.log. You will see lines like:
0:0:0:0:0:0:0:1%0 - - [21/01/2010:15:08:29 +0000] "GET /solr/select/?q=*:*&qt=geo&lat=45&long=15&radius=10 HTTP/1.1" 200 197
In this case, you can parse out that the user was doing a q=: search! Use a tool like AWStats to parse your logs and do the analysis. It's at least a quick and easy way to get some information!

Months later ... maybe someone is interested:

(you'll need to adapt the log parser if you are not using the default solr output format)

The SolrLogging wiki page says you can use JDK logging (in Solr 1.0 to 1.3) or slf4j logging in Solr 1.4. About your own Solr analyzer - it depends on your needs. In many cases, using your own analyzer helps for specific retrieval requirements.

You can look at something like logstash to parse your log data.
