| string |
| file_storage::search_references | ( | $reference | ) |
Returns all aliases that refer to some stored_file via the given reference.
All repositories that provide access to a stored_file are expected to use self::pack_reference(). This method can't be used if the given reference does not use this format or if you are looking for references to an external file (for example it can't be used to search for all aliases that refer to a given Dropbox or Box.net file).
Aliases in user draft areas are excluded from the returned list.

All repositories that provide access to a stored_file are expected to use self::pack_reference(). This method can't be used if the given reference does not use this format or if you are looking for references to an external file (for example it can't be used to count aliases that refer to a given Dropbox or Box.net file).
Aliases in user draft areas are not counted.

The query parameter will be used in conjuction with the SQL directive LIKE, so include '' in it if you need to. This search will always ignore user files and directories. Note that the search is case insensitive.
This query can quickly become inefficient so use it sparignly.
| string | $query | The string used with SQL LIKE. |
| integer | $from | The offset to start the search at. |
| integer | $limit | The maximum number of results. |
| boolean | $count | When true this methods returns the number of results availabe, disregarding the parameters $from and $limit. |
