Search solution How to install and configure solr+php?

Question

solr+php How to install, configure and use

Solution 1:

solr provides http request query interface. The client obtains data in json, xml and other data formats by triggering http requests, and parses and displays the data. Generally, various languages ​​will have encapsulated client plug-ins, such as Java's solrj, Python's solrpy, and PHP's php-solr-client, which can be indexed and queried according to the provided API. As for the installation and configuration of solr, you can read the solr cookbook.

Solution 2:

I want to make the php program use solr search. I was worried at first

I don’t know how What to do with java?
How to create an index for the search system?
How to write code in php?

solr is written in java. It is a server program with a management interface and provides http interface.
In addition to the configuration file, there is no need to write java code. PHP has solr extensions.

So, it is quite simple. 1. Install solr and verify You have installed it
Refer to Installing Solr5.3 under CentOSsolr5.3 is already a separate server, including the web management background, so it is very good
Just make sure your linux has jdk
Download the solr5.3 package directly. Apache Download Mirrors
Be sure to download solr5.3.tgz like this. Do not download the src package, and then unzip it to get a directory like solr5.3

The two most critical points for installation 1. You can use it without unzipping. There is a directory in the solr directory. The install script needs to be run, and the data directory must be specified (to store the index) 2. Solr has a concept of core, which can be understood as db in the database. You can create a core. This also has a script, but you must ensure that the data directory has the permissions of the solr user.

# solr-5.3.0/bin/install_solr_service.sh solr-5.3.0.tgz -d /data/solr -i /usr/local

-i indicates where you installed the solr server

# su - solr -c "/usr/local/solr/solr/bin/solr create -c corename

Create your own core

service solr start Start the service

http://yourip::8983/solr This is management Interface

2, design your own search index

http://yourip::8983/solr This is the management interface, select the core you createdJust focus on add Documents and query, add index in one thing Query one thing, very easy to understand

add Documents interface, there are already examples, two fields id and title are indexed, you can change the data submission

Query interface q=*:* to query all

q=title:a* to query title

It’s easy to understand after playing a few times for

Now there are id and title. I want to add a field of my own, what about type?

Go to the data directory and grep "title", and find the configuration items of id and title, similar to ：

Please fill in the type as shown below

service solr stop/start restart the service

Go back to the management interface and add data. Suppose you want to jointly search title and type

Then q= title:xx 2 studies, basically can create data, find the data and now write a php program to complete these functions
Reference: PHP: Solr - Manual
SolrInputDocument input document

SolrClient This is the user to connect to the solr server

SolrQuery This is to build the search conditions Go directly to the program:

class  Search
{
	private $client;
	public function __construct() {
            $options = 
            [
                'hostname' => 'localhost',   //solr服务器的ip
                'path' => 'solr/corename',  //这个解决core的问题，corename就是你的core
                'wt' => 'json',
            ];
$this->client = new \SolrClient($options); 
	}
public function addIndex($id, $type, $content) {//加索引的函数
            $doc = new \SolrInputDocument();
$doc->addField('id', $type . "." . $id); //保证id唯一我把type加上了
            $doc->addField('type', $type);
            $doc->addField('title', $content);
            $client = $this->client;
$updateResponse = $client->addDocument($doc);
            $client->commit();  //一定要commit才能立即生效
$ret = ($updateResponse->getResponse());
            if ( isset($ret->responseHeader['status']) ) {
                return $ret->responseHeader['status'] == 0?true:false;
            }
             return false;
        }
public function search($key, $type=0, $page=0, $limit=15) {
            $query = new \SolrQuery();
$query->setQuery('title:' . $key . "*"); //这个是设置keyword
	    $query->setStart($page); //分页的
            $query->setRows($limit);
            if($type) {
                $query->addFilterQuery('type:' . $type);  //用到fq了
            }
            $query->addField('id')->addField('title')->addField('type'); //这里是你要查哪些字段
            $client = $this->client;
            $query_response = $client->query($query);
$response = $query_response->getResponse();
            $response = ($response->response);
            if ( is_array($response->docs) ) {
                foreach($response->docs as &$doc) {
                    $id = explode(".", $doc->id);
                    if( isset($id[1]) ) {
                    $doc->id = $id[1];
                    }
                    $doc->type = isset($doc->type[0])?$doc->type[0]:'';
                }
            }
            return ($response);
        }
}
