Do a query on the full-text search index for a word or words.
This function is normally only called by each module that supports the indexed search (and thus, implements hook_update_index()).
Results are retrieved in two logical passes. However, the two passes are joined together into a single query. And in the case of most simple queries the second pass is not even used.
The first pass selects a set of all possible matches, which has the benefit of also providing the exact result set for simple "AND" or "OR" searches.
The second portion of the query further refines this set by verifying advanced text conditions (such as negative or phrase matches).
The used query object has the tag 'search_$module' and can be further extended with hook_query_alter().
