But you will need to configure your build to include SolrJ and its dependencies.

Most mainstream build systems greatly simplify dependency management, making it easy to add SolrJ to your project. For projects built with Ant using Ivyplace the following in your ivy. At build time, all that is required is the SolrJ jar itself: solr-solrj To compile code manually that uses SolrJ, use a javac command similar to:.

Run your project with a classpath like:. If you are worried about the SolrJ libraries expanding the size of your client application, you can use a code obfuscator like ProGuard to remove APIs that you are not using.

All requests to Solr are sent by a SolrClient. They handle the work of connecting to and communicating with Solr, and are where most of the user configuration happens. Requests are sent in the form of SolrRequestsand are returned as SolrResponses. SolrClient has a few concrete implementations, each geared towards a different usage-pattern or resiliency model:. HttpSolrClient - geared towards query-centric workloads, though also a good general-purpose client. Communicates directly with a single Solr node.

Adjusts the list of "in-service" nodes based on node health. CloudSolrClient - geared towards communicating with SolrCloud deployments. Uses already-recorded ZooKeeper state to discover and route requests to healthy Solr nodes. ConcurrentUpdateSolrClient - geared towards indexing-centric workloads. Buffers documents internally before sending larger batches to Solr. Most SolrJ configuration happens at the SolrClient level.

For comprehensive information on how to tweak your SolrClientsee the Javadocs for the involved client, and its corresponding builder object. The path users include on the base URL they provide has an effect on the behavior of the created client from that point on.

A URL with a path pointing to a specific core or collection e. When a core or collection is specified in the base URL, subsequent requests made with that client are not required to re-specify the affected collection. A URL pointing to the root Solr path e.

All SolrClient implementations allow users to specify the connection and read timeouts for communicating with Solr. These are provided at client creation time, as in the example below:. SolrClient has a number of query methods for fetching results from Solr.In previous tutorials, we have seen how to install Apache Solr on windows 10 and created solr core sample-items.

Leave A Comment Cancel reply Comment.SolrJ hides a lot of the details of connecting to Solr and allows your application to interact with Solr with simple high-level methods. The center of SolrJ is the org. Begin by creating a SolrClientwhich represents the Solr instance you want to use. Once you have a SolrClientyou can use it by calling methods like queryaddand commit. However, in order to build and run applications that use SolrJ, you have to add some libraries to the classpath.

At build time, the examples presented with this section require solr-solrj-x. The Ant script bundled with this sections' examples includes the libraries as appropriate when building and running. If you are worried about the SolrJ libraries expanding the size of your client application, you can use a code obfuscator like ProGuard to remove APIs that you are not using.

SolrJ uses a binary format, rather than XML, as its default response format. If you are trying to mix Solr and SolrJ versions where one is version 1. The binary format changed in 3. The following code will make this change:. Use query to have Solr search for results.

You have to pass a SolrQuery object that describes the query, and you will get back a QueryResponse from the org. SolrQuery has methods that make it easy to add parameters to choose a request handler and send parameters to it. Here is a very simple example that uses the default request handler and sets the query string:. To choose a different request handler, there is a specific method available in SolrJ version 4. You can also set arbitrary parameters on the query object.

The first two code lines below are equivalent to each other, and the third shows how to use an arbitrary parameter q to set the query string:. The client makes a network connection and sends the query. Solr processes the query, and the response is sent and parsed into a QueryResponse. The QueryResponse is a collection of documents that satisfy the query parameters.

You can retrieve the documents directly with getResults and you can call other methods to find out information about highlighting or facets. Other operations are just as simple. This example assumes that the SolrClient object called 'solr' is already created based on the examples shown earlier.

SolrJ lets you upload content in binary format instead of the default XML format. Use the following code to upload using binary format, which is the same format SolrJ uses to fetch results. When implementing java applications that will be bulk loading a lot of documents at once, ConcurrentUpdateSolrClient is an alternative to consider instead of using HttpSolrClient.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I have tested the same on remote machine solr instance, localhost having data index on remote solr [inside java commented].

You are committing every new document, which is not necessary. On my machine, this indexes your records in 14 seconds. If I remove the commit call from the for loop, it indexes in 7 seconds. Alternatively, you can add a commitWithinMs parameter to the solrCloudClient. This will guarantee your records are committed within 15 seconds, and also increase your indexing speed.
