I am using following code in my controller (i.e SearchResultController.jpf)
I have hardcoded string value (i.e SearchString)
Search search = new Search("SearchString");
search.setUseCache(false);
// Do the search using the ISearchManager.
ISearchManager searchManager = ContentManagerFactory.getSearchManager();
ContentContext ctx= new ContentContext(getRequest());
          ctx.setParameter( ICMPagedResult.PAGE_SIZE_KEY, new Integer(5) ); // use pages of size 5
// find the search results
          ISortableFilterablePagedList<Node> resultList = searchManager.search(ctx, search);
CMPagedResultFactory<Node> pagedResultFactory= new CMPagedResultFactory<Node>();
     ICMPagedResult<Node> pagedResults= pagedResultFactory.createPagedResult( ctx, resultList );
Kindly tell me what is wrong.
Also How will i use Expression in case of String

Answer 1

Hi greg
thanks for the reply.
i got something about Search class. But i am again back to zero as i am not getting any search results.
Following is the code i am using in controller class
String keywordVal= "searchString";
IMetadataQuery mQuery = FullTextQueryFactory.getMetadataQuery();
ITextQuery tQuery = FullTextQueryFactory.getTextQuery();
IFullTextSearch fts = FullTextSearchFactory.buildFullTextSearch(
null, /*mQuery.buildContains("*", new String[]{keywordVal}) Metadata query parameter, match any field with the given string */
tQuery.buildEquals(keywordVal), /* Text query parameter, match binary content with the given string */
true /* isOr */);
//create the search path
String repositoryPath = PathHelper.SEPARATOR + "BEA Repository";
//create the search object
Search search = new Search(repositoryPath, -1, null, fts, true );
// Do not use the global search cache.
search.setUseCache(false);
// Do the search using the ISearchManager.
ISearchManager searchManager = ContentManagerFactory.getSearchManager();
ContentContext ctx= new ContentContext(getRequest());
          ctx.setParameter( ICMPagedResult.PAGE_SIZE_KEY, new Integer(5) ); // use pages of size 5
// find the search results
          ISortableFilterablePagedList<Node> resultList = searchManager.search(ctx, search);
CMPagedResultFactory<Node> pagedResultFactory= new CMPagedResultFactory<Node>();
     ICMPagedResult<Node> pagedResults= pagedResultFactory.createPagedResult( ctx, resultList );
     iterator = resultList.iterator();
// We will forward the payload along. This is currently used by the displayResults portlet.
// The displayResults portlet listens for the pageflow action "findResults". In response it fires
// its own pageflow action which will display the results.
return new Forward("success");
and i have also changed something in content-config.xml which looks something like this: -
<?xml version="1.0" encoding="UTF-8"?>
<content-config xmlns="http://www.bea.com/ns/portal/90/content-config">
<!-- This is a default content repository applications can use.
The IDE should copy this to META-INF/content-config.xml of the

<binary-cache-max-entry-size>1024</binary-cache-max-entry-size>
<!-- metadata search -->

<!-- full text search -->
<fulltext-search-is-enabled>true</fulltext-search-is-enabled>
<search-indexing-is-enabled>true</search-indexing-is-enabled>
</content-store>
</content-config>
Kindly tell me if i have to change anything somewhere else.
because from this code i am not getting any results
thanks
