Adding metadata to nodes for SOLR search We have a website using SOLR search and we've run across an issue. For example, we have a page called "Organizational Chart" but if someone searches for "org chart" it will not appear in search results.

Is there a way to add aliases or metadata to nodes so that we can add "might be searched by" data or extra information that may enhance search visibility?

Would simply adding a cck field accomplish something like this? Taxonomy doesn't really apply because these are not categories and would be different across each node.
Apache Solr supports synonyms, and you can add them to the solr/conf/synonyms.txt file.  The path is relative to where you copied the "example" directory to.  This way people searching for "org chart" would find documents containing "Organization Chart" and any other synonyms you wish to add without any modifications to Drupal.
