Example of how you could search for pages.

    public class PageSearchSample : TemplatePage
{
public IEnumerable<PageData> FindPages(string searchQuery, ContentReference searchRoot, string cultureId, int pagingNumber, int pagingSize)
{
    // The group query is needed to combine the different criteria
    GroupQuery groupQuery = new GroupQuery(LuceneOperator.AND);
// The content query makes sure we only get hits that are of the type PageData
groupQuery.QueryExpressions.Add(new ContentQuery&lt;PageData>());

// The field query contains the search phrase
groupQuery.QueryExpressions.Add(new FieldQuery(searchQuery));

// The virtual path query makes sure that we only get hits for children of the specified search root
VirtualPathQuery pathQuery = new VirtualPathQuery();
pathQuery.AddContentNodes(searchRoot);
groupQuery.QueryExpressions.Add(pathQuery);

// The access control list query will remove any pages the user doesn&apos;t have read access to
AccessControlListQuery aclQuery = new AccessControlListQuery();
aclQuery.AddAclForUser(PrincipalInfo.Current, HttpContext.Current);
groupQuery.QueryExpressions.Add(aclQuery);

// Add a specific field query for the Culture field in order to search for a specific culture
groupQuery.QueryExpressions.Add(new FieldQuery(cultureId, Field.Culture));

SearchResults results = Locate.SearchHandler().GetSearchResults(groupQuery, pagingNumber, pagingSize);

ContentSearchHandler contentSearchHandler = Locate.ContentSearchHandler();
foreach (var hit in results.IndexResponseItems)
{
    // Use the content search handler to convert the page hit into a PageData
    yield return contentSearchHandler.GetContent&lt;PageData>(hit);
}

}
}
