Drupal 7 Synonyms

The Synonyms module enriches Entities with the notion of synonyms. Currently the module provides the following functionality:

  • support of synonyms through Field API. Any field, for which synonyms behavior implementation exists, can be enabled as source of synonyms.
  • support of synonyms through Entity properties. Entity properties stored in database (as opposed to being calculated on-the-fly) can be enabled as source of synonyms.
  • synonyms-friendly autocomplete and select widgets for taxonomy_term_reference, entityreference, and commerce_product_reference (through Synonyms Commerce submodule) fields.
  • integration with Drupal search functionality through Synonyms Search submodule. It enables searching content by synonyms of the terms that the content references. Synonyms Search submodule also integrates with Term Search contributed module in a fashion that allows your terms to be found by their synonyms.
  • integration with Search API. If you include entity synonyms into your Search API search index, your clients will be able to find content with search keywords that contain synonyms and not actual names of entities.
  • integration with Views. Synonyms module provides a few filters and contextual filters that allow filtering not only by entity name but also by one of its synonyms. Synonyms module also provides a Views field for all eligible entities that contains a list of synonyms associated with the entity in question.

Requirements

The Synonyms module requires the following modules:

The Synonyms module integrates with (but does not require) the following
modules:

Supported synonyms providers

Module ships with ability to provide synonyms from the following locations:

  • "Text" field type
  • "Taxonomy Term Reference" field type
  • "Entity Reference" field type
  • "Commerce Product Reference" field type
  • "Number" field type
  • "Float" field type
  • "Decimal" field type
  • Entity properties stored in database

Worth mentioning here: this list is easily extended further by implementing new synonyms providers in your code. Refer to Synonyms advanced help for more details on how to accomplish it.

Granulation within synonyms behavior

In order to achieve greater flexibility, this module introduced additional
granularity into what "synonyms" mean. This granularity is expressed via
"synonyms behavior" idea whatsoever. Then you can enable different synonyms behaviors for different synonyms providers. For example, field "Typos" can be part of autocomplete behavior, while field "Other spellings" can be part of search integration behavior. Currently the following synonym behaviors are recognized (other modules actually can extend this list):

  • Autocomplete - whether synonyms from this provider should participate in autocomplete suggestions. This module ships with autocomplete synonyms friendly widgets and their autocomplete suggestions will be filled in with the synonyms of providers that have this behavior enabled.
  • Select - whether synonyms from this provider should be included in the synonyms friendly select widgets.
  • Search integration (requires Synonyms Search enabled) - allows your content to be found by synonyms of the terms it references. Your nodes will be found by all synonyms that have this behavior enabled.

Therefore, on the Synonyms configuration page you will see a table, where rows are synonym providers and columns are these "synonym behaviors" and you decide what synonym behaviors to activate on what synonym providers.

Pre 7.x-1.3 update

If you are updating minor versions of Synonyms module from < 7.x-1.3 to current stable release this section is for you. Synonyms has undergone lots of changes grasping much of new and powerful functionality which made it difficult to maintain a clear update path from < 7.x-1.3 to >= 7.x-1.5. This means you can't just update your module in a single run. Firstly you should update to 7.x-1.4 (where by "update" it is implied to update the Synonyms module files and run update.php). Once you have updated to 7.x-1.4 you can then update to the latest current stable release seamlessly. So you'll have to execute your update in 2 iterations.

For more details refer to #2741995: Version 1.5 update breaks path from pre-1.4.
