>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #200810. --> Reported by: [dman](https://www.drupal.org/user/33240) >>> <p>Task title: Integrate the existing taxonomy 'synonyms' support with Drupal search and freetagging.</p> <p>Task description: Drupal currently provides an interface for term synonyms, but those synonyms are not available or used in the system anywhere.<br> This task is in two parts, both small and highly related.</p> <p>1: Synonyms would be a very useful feature in the search.module.<br> Add a taxonomy terms synonyms to the search index function taxonomy_node_update_index()</p> <p>This would mean that upon running a search for the synonym, the nodes that are tagged with the major, cannonic term, would be returned, even though the exact synonym term itself may not appear anywhere in the node content.</p> <p>2: When using the 'freetagging' feature of taxonomy, entering a new word or phrase creates a new term entry, even if that word or phrase is a valid synonym for an existing term.<br> This creates bogus entries and duplication.<br> The behaviour should be to (optionally) 'collapse' and re-phrase the user-submitted synonym into the cannonic term.<br> 2.1: Create an interface setting to enable/disable this behaviour<br> 2.2: When a word that is detected as a viable synonym is submitted in 'freetagging' input, convert that word into its base term.<br> 2.3: Enhance the current AJAX autocomplete behaviour to offer the base term as a suggestion when a synonym is detected.</p> <p>Task 2.3 may be a little harder than it looks, as the autocomplete term lookup currently fires on all partial matches within words. In a large vocabulary, containing synonyms this could result in unintuative false positives. But investigate.</p> <p>Example, in a taxonomy of US states, a term "Virginia" may have a synonym "VA".<br> User should be able to type "VA" in a taxonomy autocomplete field and submit the node and have it matched up with "Virginia" in the database.</p> <p>Deliverables would include a patch against<br> 1: taxonomy.node taxonomy_node_update_index()<br> 2: taxonomy.node taxonomy_autocomplete() (maybe more like autocomplete.js , but that should be avoided)</p> <p>This will involve skills in search engine behaviour, meaningful metadata (taxonomy) management, and, for fun, AJAX!</p> <p>Resources: <a href="http://drupal.org/node/200751">http://drupal.org/node/200751</a></p> <p>Primary contact: dman</p>
