Using Python to Operate Apache Solr
To operate the Apache Solr database using Python, you need to first install Solr's Python library, which is called 'pysolr'. You can use the following command to install:
pip install pysolr
Next, you can use the following code example to operate the Apache Solr database.
###Connect to Solr
Before using 'pysolr', you need to connect to the Solr server:
python
import pysolr
#Connect to Solr server
solr = pysolr.Solr('http://localhost:8983/solr/', timeout=10)
###Insert Data
The following is an example code for inserting data into Solr:
python
doc1 = {
"id": "1",
"title": "Example Document 1",
"content": "This is the content of document 1."
}
doc2 = {
"id": "2",
"title": "Example Document 2",
"content": "This is the content of document 2."
}
#Insert Document into Solr
solr.add([doc1, doc2])
###Query data
The following is an example code for querying Solr data:
python
#Query all documents
results = solr.search('*:*')
#Print query results
for result in results:
print(f"Document ID: {result['id']}, Title: {result['title']}, Content: {result['content']}")
###Modify data
The following is an example code for modifying Solr data:
python
#Update content based on document ID
solr.add([
{
"id": "1",
"content": "This is the updated content of document 1."
},
{
"id": "2",
"content": "This is the updated content of document 2."
}
])
###Delete data
The following is an example code for deleting Solr data:
python
#Delete document based on document ID
solr.delete_by_id("1")
#Submit deletion operation
solr.commit()
You can further use 'pysolr' to operate the Solr database according to your own needs.
