Transfer data from solr to python

Question

I am beginner to solr.i want to transfer the data from solr to python and i have found the pysolr library i have installed it but did'nt know how to use it. I have searched on google but did'nt find required answer

I want to ask how we can load data from solr to python and perform filtering,sorting and other operations

i have tried as:

from pysolr import Solr
conn = Solr('/localhost:8983/solr/sms_data/select?indent=on&q=customer_id:73614&rows=10&start=0&wt=json')

Now how can i read the data present in conn and perform other operations.

Your example is the complete Solr query string. That's not how you use pysolr. From pysolr's README (adapter to your example):

# Setup a Solr instance. 
solr = pysolr.Solr('http://localhost:8983/solr/sms_data')

results = solr.search('customer_id:73614')

for result in results:
    print(result)

Further functionality can be added as parameters to the .search method, such as fq (you'll have to use the kwargs-style if you want to include parameters with . in them):

results = solr.search('customer_id:73614', fq='field:value')

# or

result = solr.search('*:*', **{
    'fl': 'content',
    'facet': 'true',
    'facet.field': 'field_name'
})
