 /**
  * Select a set of records from table and fetch the first one
  * @param $query Optional array of (field => value) or (int => sqlstring) pairs. Defaults to null (select all records)
- *           Fields are joined by AND
- *           Fields can contain a compare operator, e.g. 'name LIKE' or 'amount >'
+ *           Fields will be joined by AND
+ *           Fields can contain a compare operator: 'name LIKE' => "j%" or 'amount >' => 100
+ *           Fields can start with - to prevent quoting of right side: '-modified' => "CURDATE()"
  *           $query can contain magic field 'SELECT' for things like 'COUNT(*)' or 'DISTINCT foo', defaults to '*'
  *           $query can contain magic field 'JOIN' for things like 'tableA LEFT JOIN tableB ON a=b', defaults to table name
- *           $query can contain 'CALC_FOUND_ROWS', if true member var _found_rows contains number of matching rows without LIMIT
+ *           $query can contain 'CALC_FOUND_ROWS', if true member var _found_rows contains number of matching rows before LIMIT
  *           $query can contain 'NOFETCH', if true the first row is not prefetched (e.g. when directly using _result)
  * @return Number of matching rows, use iterate() to fetch the next record
  * @see iterate()
