solrpy 0.9.11

Client for the Solr search service

solrpy

solrpy is a Python client for Solr, an enterprise search server built on top of Lucene. solrpy allows you to add documents to a Solr instance, and then to perform queries and gather search results from Solr using Python.

• Supports Solr 1.2 through 10.x
• Automatic Solr version detection with runtime feature gating
• Python 3.10+ required

Installation

pip install solrpy

Or with Poetry:

poetry add solrpy

Overview

import solr

# create a connection to a solr server
s = solr.Solr('http://localhost:8983/solr/mycore')

# the server version is auto-detected
print(s.server_version)  # e.g. (9, 4, 1)

# check if the server is reachable
print(s.ping())  # True

# add a document to the index
doc = {
    "id": 1,
    "title": "Lucene in Action",
    "author": ["Erik Hatcher", "Otis Gospodnetić"],
}
s.add(doc, commit=True)

# do a search
response = s.select('title:lucene')
for hit in response.results:
    print(hit['title'])

More powerful queries

Optional parameters for query, faceting, highlighting, and more like this can be passed in as Python parameters to the query method. Convert the dot notation (e.g. facet.field) to underscore notation (e.g. facet_field) so that they can be used as parameter names.

response = s.select('title:lucene', facet='true', facet_field='subject')

If the parameter takes multiple values, pass them in as a list:

response = s.select('title:lucene', facet='true', facet_field=['subject', 'publisher'])

Version detection

solrpy automatically detects the connected Solr version and gates features accordingly. If a feature requires a newer Solr version than what is connected, a SolrVersionError is raised with a clear message.

import solr

s = solr.Solr('http://localhost:8983/solr/mycore')
print(s.server_version)  # (6, 6, 6)

Tests

Tests require a running Solr instance. Using Docker:

docker run -d --name solr-dev -p 8983:8983 solr:6.6 solr-precreate core0
poetry run pytest tests/
