Initiate a search on the given columns. C<type> can be one of C<exact>, |
| 21 |
|
|
C<prefix>, C<like>, C<regexp> or C<match>, which specifies the sql-search |
| 22 |
|
|
mode used. For C<nummer>-columns, only C<exact> and C<prefix> are |
| 23 |
|
|
supported. |
| 24 |
|

Returns a C<dinfo::result> object. |

Not all types are efficient on all columns.. check your indices! :) |
