Simple Solr Node Client Project
npm install solr-node
- Client: http://godong9.github.io/solr-node/docs/Client.html
- Query: http://godong9.github.io/solr-node/docs/Query.html
// Require module
var SolrNode = require('solr-node');
// Create client
var client = new SolrNode({
host: '127.0.0.1',
port: '8983',
core: 'test',
protocol: 'http'
});
// Set logger level (can be set to DEBUG, INFO, WARN, ERROR, FATAL or OFF)
require('log4js').getLogger('solr-node').level = 'DEBUG';Search can be executed with a simple text query or an object query.
Text queries are similar to what one would find on the SOLR Core UI, EX:
From the URL: http://localhost:8080/solr/products/select?q=*:*&wt=json
The Query would be:
*:*&wt=json
NOTE: url decoded ':' from :.
Object based queries can be simple or complex using chaining. Each method of the Query object returns an instance of itself.
Examples:
Simple:
client.query().q({text:'test', title:'test'});
Complex and chained:
client.query()
.q({text:'test', title:'test'})
.addParams({
wt: 'json',
indent: true
})
.start(1)
.rows(1)
;
// Create query
var strQuery = client.query().q('text:test');
var objQuery = client.query().q({text:'test', title:'test'});
var myStrQuery = 'q=text:test&wt=json';
// Search documents using strQuery
solrClient.search(strQuery, function (err, result) {
if (err) {
console.log(err);
return;
}
console.log('Response:', result.response);
});
// Search documents using objQuery
solrClient.search(objQuery, function (err, result) {
if (err) {
console.log(err);
return;
}
console.log('Response:', result.response);
});
// Search documents using myStrQuery
solrClient.search(myStrQuery, function (err, result) {
if (err) {
console.log(err);
return;
}
console.log('Response:', result.response);
});// JSON Data
var data = {
text: 'test',
title: 'test'
};
// Update document to Solr server
client.update(data, function(err, result) {
if (err) {
console.log(err);
return;
}
console.log('Response:', result.responseHeader);
});// Delete Query
var strQuery = 'id:testid'
var objQuery = {id:'testid'}
// Delete document using strQuery
client.delete(strQuery, function(err, result) {
if (err) {
console.log(err);
return;
}
console.log('Response:', result.responseHeader);
});
// Delete document using objQuery
client.delete(objQuery, function(err, result) {
if (err) {
console.log(err);
return;
}
console.log('Response:', result.responseHeader);
});Skip the callback to get a promise back. ie:
var result = solrClient.search(query)
.then(function(result) {
console.log('Response:', result.response);
})
.catch(function(err) {
console.error(err);
});You can also use async/await:
try {
const result = await solrClient.search(query);
console.log('Response:', result.response);
} catch(e) {
console.error(err);
