How we changes standard query handler

问题

I am using solrnet I have created a new handler and want to change standard query handler "select" to "new" without using any extra parameter like "qt" or defType.

Currently "http://localhost:8080/solr/select?q=:"

Want "http://localhost:8080/solr/new?q=:"

Please advise me this is possible or not?

The post Changing Handler Endpoint in SolrQueryExecutor in the SolrNet Google Groups states that in order to do this you will need to modify the SolrQueryExecutor as described:

Question: On our Solr instance we have changed the search endpoint from "/ select" to "/search". I see in SolrQueryExecuter that there is a Handler property that just returns the DefaultHandler of "/select". Is there any way to change this to use my endpoint?

Answer: That's correct, you need to change that property in SolrQueryExecuter. How you do that depends on your IoC container. For example, with the built-in container you'd Remove() ISolrQueryExecuter and add your own with the changed handler property. This is a quite rare thing to do, usually I just set up different request handlers not as endpoints but as regular names, then you can use the qt parameter to select one.

If all you want is to invoke a different request handler, you can just get an instance of ISolrQueryExecuter and set the Handler accordingly. No need to replace the built-in SolrQueryExecuter with a concrete decorator.

Startup.Init<T>(new SolrConnection("http://localhost:8080/solr")),

var executor = ServiceLocator.Current.GetInstance<ISolrQueryExecuter<T>>() as SolrQueryExecuter<T>;
executor.Handler = "/new";

BTW, your url seems to be missing the name of the collection.
