Solr includes an output format specifically for Python, but JSON output is a little more robust.
Simple Python
Making a query is a simple matter. First, tell Python you will need to make HTTP connections.
from urllib2 import *Now open a connection to the server and get a response. The wt query parameter tells Solr to return results in a format that Python can understand.
connection = urlopen('http://localhost:8983/solr/collection_name/select?q=cheese&wt=python')
response = eval(connection.read())Now interpreting the response is just a matter of pulling out the information that you need.
print response['response']['numFound'], "documents found."
# Print the name of each document.
for document in response['response']['docs']:
print " Name =", document['name']Python with JSON
JSON is a more robust response format, but you will need to add a Python package in order to use it. At a command line, install the simplejson package like this:
sudo easy_install simplejsonOnce that is done, making a query is nearly the same as before. However, notice that the wt query parameter is now json, and the response is now digested by simplejson.load().
from urllib2 import *
import simplejson
connection = urlopen('http://localhost:8983/solr/collection_name/select?q=cheese&wt=json')
response = simplejson.load(connection)
print response['response']['numFound'], "documents found."
# Print the name of each document.
for document in response['response']['docs']:
print " Name =", document['name']
