function apachesolr_taxonomy_term_update in Apache Solr Search 8

Same name and namespace in other branches

1. 7 apachesolr.module \apachesolr_taxonomy_term_update()

Implements hook_term_update().

Mark nodes as needing re-indexing if a term name changes.

Performance issue with Mysql To know why PDO in drupal does not support UPDATE and JOIN at once. @todo the rest, such as term deletion.
