Enabling value search

You enable a standard attribute for value search by changing the values in the mdex-property-IsPropertyValueSearchable attribute in the PDR.

Managed attributes are always enabled for value search in the Oracle Endeca Server. In addition, you can also enable standard attributes of type string for value search. In this case, these attributes are searched by the Oracle Endeca Server. Only the standard attributes of type string can be enabled for value search.

The mdex-property-IsPropertyValueSearchable attribute in the PDR specifies whether an attribute in your data set is value searchable. The valid settings for this attribute are:
  • true means that the attribute is enabled for value search. This is the default.
  • false means that the attribute is not enabled for value search.

If, in addition to enabling value search for specific attributes of type string, you also would like to enable wildcard search for all value search queries, set the mdex-config_EnableValueSearchWildcard attribute in the Global Configuration Record (GCR) to true.

To enable value search, you can send a request to change the attribute in the PDR using the Configuration Web Service, or you can use Integrator ETL.

For information on how to use the Configuration Web Service, see the section in this guide and the Oracle Endeca Server API References (which contains documentation for the WSDL).

For information on how to use Integrator ETL to enable a standard attribute for value search, see the Oracle Endeca Information Discovery Integrator ETL User's Guide.

Note that you can use the data domain --search-char-limit configuration flag to specify the maximum length (in characters) of a search term for value search. The default is 132 characters. Any term exceeding this length will not be indexed for any form of value search. Keep in mind that you specify this flag via the a put-dd-profile command.
