EOL notice! Acquia Search with Solr 3/4 will reach end-of-life on Tuesday, March 1, 2022. For more information, see Frequently Asked Questions (FAQ) regarding End of Support for Acquia Search with SOLR 3/4.

For more information on upgrading from Acquia Search with Solr 3/4 to Acquia Search with Solr 7, see Upgrading Drupal 9 to Acquia Search with Solr 7 or Upgrading Drupal 7 to Acquia Search with Solr 7.

What are the benefits of upgrading to Acquia Search with Solr 7?

This upgrade to Acquia Search with Solr 7 features many improvements to Acquia’s Search services, including:

  • The Acquia Search Solr module, enabled with Solr 7 and supporting Drupal 7.x and Drupal 9.x applications.
  • Improved resiliency and security for Acquia Search services.

What parts of my website does Acquia Search include in the search index?

When you configure Acquia Search, you decide what entity types get included in the search index and are available to return to users as search results. Examples include nodes like articles, pages, and blocks, taxonomy terms, users, and files. You can include file attachments, if you install and configure the Drupal 7 Apache Solr Search Attachments module.

Can I search using logical operators?

Yes, Acquia Search uses the Apache Lucene Query Parser Syntax.

Can I search using wildcards?

Yes, you may use \* (several characters) and ? (single character) wildcards. Searches may not begin with wildcards or other logical operators.

Does Acquia Search support attachment indexing?

Yes. This feature requires installing and configuring the Apache Solr Search Attachments module. For setup and configuration information, see Indexing attachments with Apache Solr Search module.

Does Acquia Search support multisite search? Can I combine multiple content indexes from multiple hosts in the search results on my website?

Yes. This feature requires installing and configuring the Apache Solr Multisite Search module.

My website doesn’t run in English; what can I expect?

Acquia Search can index websites in most languages, but Acquia Search passes content through a language-specific stemmer during indexing, depending on the search schema you have configured for your website. Acquia Search offers search schemas for Dutch, French, German, Spanish, and English. You can search other languages, but the search may produce less relevant search results because partial words, plurals and other variations may not be indexed as expected. For more information, see Selecting a language.

If your website is in a language other than Dutch, English, French, German, or Spanish, contact Acquia Support to see whether a search schema specific to that language is available for you.

Does Acquia Search support server-side Solr configuration modifications?

You can select standard configurations on the Search page of the Acquia user interface. If you are an Enterprise customer who needs a custom configuration (typically a schema.xml or synonyms.txt file), you should open a support ticket and provide the complete configuration file. The frequency and nature of custom search configuration changes is limited. See Custom Solr configuration with Solr 3/4 for details. If you need help developing a custom configuration, contact Acquia sales to discuss your needs and implementation possibilities through Acquia’s professional services division.

Can I use the Search API module?

Yes, you can use the Search API module with Acquia Search. This is an alternative to using the Apache Solr Search module. Acquia Search for Drupal 9 or later requires the use of Search API, and won’t use the ApacheSolr module.

Don’t use both the Search API module and the Apache Solr Search module in the same environment.

For more information, read Using the Search API.

What counts as a search query toward my entitlement?

Acquia counts select (searching) and update (indexing) requests reaching the Acquia Search back end. You can view your Search usage and statistics from the Acquia Search link in the Cloud Platform user interface. For more information, see Viewing search usage and statistics.

Drupal modules can index more than one item at a time in a single Solr update request.
