Q:

Solr Search terms logs

I wanted to log Solr queries users are submitting. I could generate request logs from the solution provided in this using Jetty. 
Now, that I have the request logs (sample pasted below). Can anyone explain what does this mean q=%2A%3A%2A ? 
0.0.0.0  -  [14/Jan/2014:15:29:52 +0000] "GET /solr-nutch/hbasecollection/select?facet=true&facet.mincount=1&facet.field=source&facet.field=type&hl=true&hl.fl=title%2Ccontent&hl.simple.pre=%3Cstrong%3E&hl.simple.post=%3C%2Fstrong%3E&hl.fragsize=300&fl=%2A%2Cscore&version=1.2&wt=json&json.nl=map&q=%2A%3A%2A&start=0&rows=20 HTTP/1.1" 200 114440

A:

This value is Percent encoded. You may use URL Decoder to get the actual query. In your case, it's *:*.
