solrcount

A proxy for solr requests, that will only reveal the number of results.

$ solrcount -h
Usage of solrcount:
  -core="biblio": SOLR core name
  -host="localhost": host of the SOLR server to proxy
  -listen=":18080": host and port to listen on
  -port=8080: port of the SOLR server to proxy

host, port and core are parameters of the target SOLR server. listen is a combined host:port string, where this proxy should listen.

Starting the server:

$ solrcount -host 10.0.0.1 -port 8080 -core biblio -listen :9999

This will start a server that listens on localhost:9999 and will forward queries to a SOLR server on 10.0.0.1:8080 using the biblio core.

Querying the server:

$ curl localhost:9999
solrcount 1.0.0

$ curl localhost:9999/proxy?q=Hello
{"status":0,"qtime":0,"q":"q=Hello","count":1686}

$ curl localhost:9999/proxy?q=Hello%20World
{"status":0,"qtime":0,"q":"q=Hello","count":1686}

$ curl localhost:9999/proxy?q=Hello%20OR%20World
{"status":0,"qtime":62,"q":"q=Hello%20OR%20World","count":545878}

The query given to the proxy must be already properly escaped. Errors are signalled with a HTTP status codes:

$ curl -v localhost:18080/proxy?q="Hello World"
> GET /proxy?q=Hello World HTTP/1.1
> User-Agent: curl/7.35.0
> Host: 127.0.0.1:18080
> Accept: */*
>
< HTTP/1.1 400 Bad Request

Output can be JSON, XML or TSV, depending on the Accept header.

$ curl -H 'Accept: application/xml' localhost:9999/proxy?q=Hi
<response><status>0</status><qtime>1</qtime><q>q=Hi</q><count>4216</count></response>

$ curl -H 'Accept: text/plain' localhost:9999/proxy?q=Hi
4216

Default response mimetype is application/json.
