First of all, I want to say that not all milk is named XX Su... and not all errors are called 404...

Your error is'400' Status: Bad Request... Not 404...

In general, the cause of this error is as you said... yesSchema. xmlField...

But how to analyze it...

Apache_Solr_ServiceThis class will not return solr internal errors... so we need to solve it in other ways...

The first method is relatively simple... view solr log... there will be content similar to the following line...

SEVERE: org. apache. solr. common. SolrException :****

* *** Is the cause of the error...

The second method... use a tool that comes with solr calledsolr admin...

In this tool, you can manually enter the query... if the query is invalid, the detailed error message will be displayed...

In your description, you only need to entername:????Click OK...

With the error message, you can know how to solve this problem. Otherwise, you can only rely on the guesses of the East and the West...

Only saying that solr reports an error... you don't know why you just want others to know... sorry... I don't think anyone will know...

I'm sorry, but the truth is...

First, you must learn to describe your problems well so that others can solve the problems accurately and efficiently ..?

Note that you are callingApache_Solr_Service()Parameter passing during the constructor. One trap is that the fifth parameter is$compatibilityLayerThe parameters to be passed should be changed according to your Solr server version. For example, if you are Solr 4.0 +, the parameters should be passed.new Apache_Solr_Compatibility_Solr4CompatibilityLayer.

The reason is that the XML format generated by Solr3 and Solr4 is different. Some parameters are compatible when used, which triggersHTTP 400 Bad RequestProblem. Currently, solr-php-client uses the Solr3 standard by default.

Hope to help you.
