pysolr is a lightweight Python wrapper for Apache Solr. It provides an interface that queries the server and returns results based on the query.




  • Basic operations such as selecting, updating & deleting.
  • Index optimization.
  • "More Like This" support (if set up in Solr).
  • Spelling correction (if set up in Solr).
  • Timeout support.
  • SolrCloud awareness


  • Python 2.7 - 3.5
  • Requests 2.0+
  • Optional - simplejson
  • Optional - kazoo for SolrCloud mode


sudo python install or drop the file anywhere on your PYTHONPATH.


Basic usage looks like:

# If on Python 2.X
from __future__ import print_function
import pysolr

# Setup a Solr instance. The timeout is optional.
solr = pysolr.Solr('http://localhost:8983/solr/', timeout=10)

# How you'd index data.
        "id": "doc_1",
        "title": "A test document",
        "id": "doc_2",
        "title": "The Banana: Tasty or Dangerous?",

# Later, searching is easy. In the simple case, just a plain Lucene-style
# query is fine.
results ='bananas')

# The ``Results`` object stores total results found, by default the top
# ten most relevant results and any additional data like
# facets/highlighting/spelling/etc.
print("Saw {0} result(s).".format(len(results)))

# Just loop over it to access the results.
for result in results:
    print("The title is '{0}'.".format(result['title']))

# For a more advanced query, say involving highlighting, you can pass
# additional options to Solr.
results ='bananas', **{
    'hl': 'true',
    'hl.fragsize': 10,

# You can also perform More Like This searches, if your Solr is configured
# correctly.
similar = solr.more_like_this(q='id:doc_2', mltfl='text')

# Finally, you can delete either individual documents...

# ...or all documents.
# For SolrCloud mode, initialize your Solr like this:

zookeeper = pysolr.Zookeeper("zkhost1:2181,zkhost2:2181,zkhost3:2181")
solr = pysolr.SolrCloud(zookeeper, "collection1")

Multicore Index

Simply point the URL to the index core:

# Setup a Solr instance. The timeout is optional.
solr = pysolr.Solr('http://localhost:8983/solr/core_0/', timeout=10)

Custom Request Handlers

# Setup a Solr instance. The trailing slash is optional.
solr = pysolr.Solr('http://localhost:8983/solr/core_0/', search_handler='/autocomplete', use_qt_param=False)

If use_qt_param is True it is essential that the name of the handler is exactly what is configured in solrconfig.xml, including the leading slash if any (though with the qt parameter a leading slash is not a requirement by SOLR). If use_qt_param is False (default), the leading and trailing slashes can be omitted.

If search_handler is not specified, pysolr will default to /select.

The handlers for MoreLikeThis, Update, Terms etc. all default to the values set in the solrconfig.xml SOLR ships with: mlt, update, terms etc. The specific methods of pysolr's Solr class (like more_like_this, suggest_terms etc.) allow for a kwarg handler to override that value. This includes the search method. Setting a handler in search explicitly overrides the search_handler setting (if any).

Running Tests

The script will automatically perform the steps below and is recommended for testing by default unless you need more control.

Running a test Solr instance

Downloading, configuring and running Solr 4 looks like this:


Running the tests

The test suite requires the unittest2 library:

Python 2:

python -m unittest2 tests

Python 3:

python3 -m unittest tests
