Troubleshooting Acquia Search with Apache Solr Search module

Use the following steps when you troubleshoot issues with Acquia Search with the Apache Solr Search module:

• Attempt to connect from your local install using the subscription’s keys. You must disable and enable all the search modules to regenerate the salt variables. The step can determine if the issue is with the website or the search subscription.
• Examine the version of the Apache Solr Search module.
• If indexing appears to run fine but the results are sparse, examine /admin/settings/apachesolr/query-fields to ensure no major fields are configured to Omit. Also, scroll to the bottom of /admin/settings/apachesolr/content-bias and check which content types are excluded from indexing.

• Find the last node indexed by completing the following steps:

  1. Run the following command:

     copy

     drush -vd search-index

  2. At some point, you’ll start seeing notices about what node IDs failed to index. Run the following command and note the limit:

     copy

     drush vget apachesolr_cron_limit

  3. Divide the number returned by the previous command by 2, and then use the resulting number with the following command:

     copy

     drush vset apachesolr_cron_limit [value]

     For example, if you have 100 results, run the following command:

     copy

     drush vset apachesolr_cron_limit 50

  4. Repeat the process, halving the limit each time until you reach 1 as the returned number.

  When you reach 1, you will know which node is causing problems.

  Another technique to find the last indexed node is to use the following command:

  copy

  drush vget apachesolr_index_last

  Use the following command for Drupal 7:

  copy

  drush php-eval 'module_load_include("inc", "apachesolr", "apachesolr.index"); $rows = apachesolr_index_get_entities_to_index(apachesolr_default_environment(), "node", 1); foreach ($rows as $row) { print_r($row); }'

  The reported node is probably where the indexing problem resides.
