Introduction

The ContentService class includes a very powerful search functionality which can be used not only for a regular search of pages on a web site, but for any type of content search in the system. The search is bases on a ContentQuery which has properties like OrderBy, Depth and Text. The search result is returned as a PagedList<Content> which is a paged list of content items.

As an exmaple, you can use the Search function to get all pages of the content type News published between two specified dates and containing the phrase "customer". More examples below.

Examples

Example 1. Search for pages with the phrase "customer"

ContentQuery query = new ContentQuery();
query.Text = "customer"
PagedList<Content> result = ContentService.Search(query);

Example 2. Search for all pages of content type MyProject.ContentType.News order by created date

ContentQuery query = new ContentQuery();
query.ContentTypes.Add(ContentTypeService.Get<MyProject.ContentType.News>());
query.OrderBy.Add(new SortItem(ContentColumn.Created, SortDirection.Decending));
PagedList<Content>result = ContentService.Search(query);
            

Example 3. Search for all Products containing the phrase "car". Set the page size to 10 results and get the first page.

ContentQuery query = new ContentQuery();
query.Text = "car*";
query.ContentTypes.Add(ContentTypeService.Get<MyProject.ContentTypes.Product>());
query.PageSize = 10;
query.PageIndex = 0;
PagedList<Content> result = ContentService.Search(query);

Example 4. Search for all pages containing the phrase "car". The pages must be a descendant to the page with id 25.

ContentQuery query = new ContentQuery();
query.ParentID = 25;
query.Depth = 10;
query.Text = "car*";
PagedList<Content> result = ContentService.Search(query);

Example 5. Search for pages with a metadata value which is product = 1.

ContentQuery query = new ContentQuery();
query.MetaDataValue = new PersistedValue() { Name = "product", Type = typeof(string), Value = "1" };
PagedList<Content> result = ContentService.Search(query);
