com.bea.content.expression
Interface ISearchTranslator

public interface ISearchTranslator

Interface for third-party repositories to implement and use as a helper to translate repository-specific search syntax to/from a com.bea.content.expression.Search object. The implementation class of the repository-specific SearchTranslator must be specified in content-config.xml: <repository-property> <description>The SearchTranslator implementation specific to this repository </description> <name>SearchTranslator</name> <value>com.stellent.ridc.spi.search.SearchTranslator</value> </repository-property> <repository-property>

Field Summary

static String	PARAMETER_MAP
static String	QUERY_PARAM
static String	TRANSLATOR_CLASS

Method Summary

Search	createQuery(String queryString) Transform and set the (repository-specific) queryString into the SearchTranslator instance (which may be obtained via a Class.forName() using the class specified in content-config.xml as shown above).
Search	parameterizeSearch(Map<String,String> parameterMap) Parameterize a Search object with the given data.
ID[]	search(Search search) Execute the search using the underlying implementation.

Method Detail

search

ID[] search(Search search)
            throws Exception

Execute the search using the underlying implementation. The SearchTranslator instance is parameterized from the Search object.

Returns

array of ID representing the search results, or an empty array if none found

Throws

Exception

createQuery

Search createQuery(String queryString)

Transform and set the (repository-specific) queryString into the SearchTranslator instance (which may be obtained via a Class.forName() using the class specified in content-config.xml as shown above).

Returns

Search object that contains a reference to the SearchTranslator instance. All parameters are in the SearchTranslator instance at this point.

parameterizeSearch

Search parameterizeSearch(Map<String,String> parameterMap)

Parameterize a Search object with the given data. This sets the required search context parameters so Search can recognize the need to use a translator to perform the search. This method is used for more complex query constructions. Here is an example for parameterizing Stellent's Content Server search service for simple keyword Map<String,String> parameterMap = new HashMap<String,String>(); map.put("QueryText", "<ftx>Nederland</ftx>"); map.put("ResultCount", "20"); // defaults to 25 if not set An example for Stellent's Content Server search service for metadata Map<String,String> parameterMap = new HashMap<String,String>(); map.put("QueryText", "dDocTitle <substring> `Joshua`"); map.put("SortField", "dInDate");
