#016195: Errors when searching with Solr

The test cases run fine against the most recent versions of Solr 1.3 and 1.4, setup the way you referenced.

I can see from the code what probably goes wrong (the response is probably somehow broken), but I require a reproducing example to check what exactly happens in your case. Can you provide such?

The class I am using for interaction with the ezc search system (the article class is at the bottom):
http://pastebin.com/m645802d7

The code I used to search:
$results = titania_search::search('test');

Executing this code, I still get no error - most likely because there is nothing in the index. Please provide a minimal working reproducing script, without external dependencies.

Should work with only adding your own auto-loader to the top

I still can't reproduce the issue.

Your code executes just fine providing me one result, as expected. (Using PHP 5.3.1, Solr 1.4.0 and Java 1.6 (tried Sun VM & OpenJDK)

Can you ensure you are using the schema.xml properly and maybe clear the Solr-storage, since there might be some documents in there, which resulted from before adding the schema.xml?

I tried to index without our schema, and indexing again with our schema, and still don't get that error. Do you have more hints what you did to cause that behaviour - I would really like to be able to reproduce that bug, to fix it properly.

I copied the schema.xml file that the tutorial says to example/solr/conf/schema.xml from the example the solr site has.

I tried setting up a fresh copy of Solr with the same issue.

Backtracking a bit I went to the Search/handlers/solr.php file and in the search function, after the sendRawGetCommand call, this is what is returned:

<?xml version="1.0" encoding="UTF-8"?>

</response>

After $result = json_decode( $result );
$result is NULL

EDIT: <code></code> seems not to be working...

It looks like Solr uses its default XML response format in your case, instead of JSON, what we tell Solr to use. Can you provide me with a dump of the query parameters, in the sendRawGetCommand() method, like:

Index: handlers/solr.php
===================================================================
--- handlers/solr.php    (revision 11406)
+++ handlers/solr.php    (working copy)

     public function sendRawGetCommand( $type, $queryString = array() )
     {
+        var_dump( $queryString );
         $statusCode = 0;
         $queryPart = '';
         if ( count( $queryString ) )

PS.: The code must be in lines without any other contents for the WIT markup parser. It is quite "strict" in that regard.

The important parameter I am looking for is the "wt" => "json" part:

array(6) {
  ["q"]=>
  string(63) "ezcsearch_type_s:Document AND ( title_s:Test^2 OR body_t:Test )"
  ["wt"]=>
  string(4) "json"
  ["df"]=>
  string(0) ""
  ["fl"]=>
  string(41) "score id_s title_s ezcsearch_type_s score"
  ["start"]=>
  int(0)
  ["rows"]=>
  int(999999)
}

#265109 by Kore Nordmann on March 5th, 2010 [Permanent Link]

array(11) {
["q"]=>
string(89) "ezcsearch_type_s:titania_article AND ( title_t:test^2 OR text_t:test ) AND approved_l:"1""
["wt"]=>
string(4) "json"
["df"]=>
string(0) ""
["fl"]=>

I have no idea why Solr would return XML instead of JSON in your case. Such cases are now handled and a ezcSearchInvalidResultException is thrown.

I guess it is either a Solr bug or misconfiguration (missing JSON encoder?) you are hitting. I have no idea what to do about that in ezcSearch except for "handling" this case by throwing an exception.

Thanks for your bug report, and feedback.

If you find the reason for Solr behaving in this way, please report back, so we can add a hint to the documentation.

You seem to have missed committing a new file when you fixed this as it's included in the autoloader but doesn't exist

Search/exceptions/invalid_result.php

#265521 by Nathan Guse on March 27th, 2010 [Permanent Link]

Was just playing around to see if I could find a way to fix this and the issue seems to be from using &amp; in $queryPart in sendRawGetCommand instead of &
