Hello,

When I try to configure the default "More like this" block it seems like a field is missing :

Fields for finding related content *

There is no way of actually choosing the fields, which of course causes a validation error when I try to submit the form :

Fields for finding related content field is required.

The weird thing is, the More Like This block seems to be working just fine anyways, just the configuration that doesn't.

Seems to be working fine for me? Can you try with latest dev? Did you index your content already?

can't reproduce this - can you add a screen shot?

Note that the list of fields comes form the index.

My content in indeed indexed. I just re-indexed it with the latest dev (to fix issue #1957070: "Solr search index will be rebuilt." message appears at the top of every view. (Even when index has been completely rebuilt.)) :

Index status

Here's a screenshot from the "More Like This" block configuration page :

No fields

As you can see, I can't select any fields.

And finally, when I submit the form, I have the following error, as expected :

validation error

Right, so you are not getting the field list from the index . This admin page actually makes a request to Solr if the result is not in the cache.

Check you logs for error messages.

My reports...
I'm using Solr 4.2.1 (Jetty) in all my tests:
Test 1: Drupal 7.21 + apachesolr 1.x-dev (last)
Test 2: Drupal 6.26 + apachesolr 6.x-3.x-dev (last, with this patch from #1550964: Support Solr 4.0 schema)

- 1 error in Solr log, but related to "i18n" (image).
- In both cases, no errors in Drupal log and I had the same result as @Growiel.

I don't have anything in the logs, neither in Apache logs, Drupal reports or Solr logs.

However, I went ahead and searched the cause of the problem and located it :

function apachesolr_search_mlt_get_fields() {
  $rows = array();

  try {
    $solr = apachesolr_get_solr();
    $fields = $solr->getFields();
    foreach ($fields as $field_name => $field) {
      if ($field->schema{4} == 'V') {
        $rows[$field_name] = apachesolr_field_name_map($field_name);
      }
    }
    ksort($rows);
  }
  catch (Exception $e) {
    watchdog('Apache Solr', nl2br(check_plain($e->getMessage())), NULL, WATCHDOG_ERROR);
  }

  return $rows;
}

The faulty part is the $field->schema{4}.

I var_dumped my fields and V only appears in 5th position :

string(7) "content" string(16) "ITS--V----------"
string(5) "label" string(16) "ITS--V--O-------"
string(10) "path_alias" string(16) "ITS--V--O-------"
string(14) "taxonomy_names" string(16) "IT--MV--O-------"
string(15) "tm_vid_10_names" string(16) "ITS-MV----------"

and so on.

This also explains why there's nothing in the logs : Solr does return something, it's the php part that ends up returning an empty array.

I don't know Solr well enough, but might this be due to the way Solr 4.x works as opposed to 3.x / 1.4 ?
Is this due to my own implementation (since I'm not the only one having the problem, I doubt it) ?

Hope that helps !

Any update on this ? Do you want me to submit a patch changing 4 to 5 ?

I was experiencing the same issue.

configuration:

- Drupal 7.21
- Apache SOLR integration - 7.x-1.2
- SOLR 3.6.2

I made the change you suggested (changing 4 to 5) and now the field boxes appear. Thanks for your help.

For anyone who wants to implement this update, the document of reference is apachesolr_search.module located in the apachesolr module.

So this is a difference between solr 3 and 4? We should use the getSolrVersion function to see how we react on the different outputs

Growiel commented

Doesn't looks like it since I use Solr4 and justluvgod is using Solr3.

I can confirm that changing
if ($field->schema{4} == 'V') {
to
if ($field->schema{5} == 'V') {
in apachesolr_search_mlt_get_fields() does work for Solr 4. (Module: 7.x-1.2)
I agree, Solr version has to be checked in this function.

It would seem the position is not significant, just the letter?

Solr 3.6.2 has this key, which indicates each letter is unique:

  "info":{
    "key":{
      "I":"Indexed",
      "T":"Tokenized",
      "S":"Stored",
      "M":"Multivalued",
      "V":"TermVector Stored",
      "o":"Store Offset With TermVector",
      "p":"Store Position With TermVector",
      "O":"Omit Norms",
      "F":"Omit Term Frequencies & Positions",
      "P":"Omit Positions",
      "L":"Lazy",
      "B":"Binary",
      "f":"Sort Missing First",
      "l":"Sort Missing Last"},
    "NOTE":"Document Frequency (df) is not updated when a document is marked for deletion.  df values include deleted documents."}}
