Here is a sample code for highlighting the results for search keyword harry. Solr can be used to highlight the fields returned in a search result based on the query. Highlighting search results using PHP and Solr Also facets can be created based on fields in the index and it can be used by the end users to narrow down the results. In addition to these, Solr provides a way of narrowing down the results using filter queries. Score is calculated for each document in the result set using two main factors – term frequency known as tf and inverse document frequency known as idf. If no sorting is provided, the Solr results are sorted by the score of documents which are calculated based on the terms in the query and the matching terms in the documents in the index. We can also use function queries to do some type of dynamic boosting based on values in fields. With the help of these query modes, we can boost certain fields to give more importance to certain fields in our query. In addition to this simple select query, Solr also supports some advanced query modes known as dismax and edismax. Pagination has been implemented as 3 results per page, so this query returns results for 2nd page starting from 3rd result. The results are sorted in ascending order or price and fields returned are id, name of book, price and author of book. The above code creates a simple Solr query and searches for book in cat field and Martin in author field. $query = $client->createSelect($selectConfig) 'query' => 'cat:book AND author:Martin', 'start' => 3, 'rows' => 3, Document added to Solr index Executing search on Solr Indexĭocuments added to the Solr index can be searched using the following piece of PHP code.
$updateQuery->addDocuments(array($doc1)) Īfter executing the code, a search for martin will give these documents in the result.
#Solr php suggester update
So we will have to keep different values for Id field for different documents that we add to Solr.Īdd documents to the update query followed by commit command. Id field has been marked as unique in our schema. $doc1->series_t = '"A Song of Ice and Fire"' Create the document in PHP and finally add fields to the document. Let us see a small piece of code for adding documents to the Solr index using PHP and Solarium library.Ĭreate a solarium client. It defines how each field will be treated and handled during indexing or during search. Schema consists of fields and field types. But before we create a Solr index, we need to define the structure or the schema of the Solr index. To create a Solr index, we need to add documents to the Solr index using the command line, Solr web interface or our PHP program. Output of ping query using PHP Adding documents to Solr index The output should be similar to the one shown below. And call the createPing() function to create the ping query.įinally execute the ping query and get the result. Next we will need to create a Solarium client with the previous Solr configuration. And defined the connection parameters for our Solr server. We have included the Solarium library in our code. $config = array("endpoint" => array("localhost" => array To execute the same query on Solr using the Solarium library the code is as follows. Though Curl can be used to execute almost any query on Solr, but it is preferable to use a library which does the work for us. We can use Curl to get the ping response from Solr via PHP code a sample code for executing the previous ping query is as belowĬurl_setopt($curl, CURLOPT_RETURNTRANSFER, 1) Įcho "Ping Status : ".$data.PHP_EOL
