Yes, you should indeed do so.

What does the Search Engine work on?

To get the most out of WebSite X5's built-in Search Engine you need to know that:

▪Pages

The items that the Search Engine considers in a page are the title, description and keywords (see the Page Properties | General window), as well as the text contents.

▪Images / Videos

The Search Engine only considers images and videos that have been added to the SiteMap (see Image Object | Sitemap or Video/Audio Object | Sitemap) and it analyzes all the information that has been given: Title, Caption and Geographical position (e.g. Address, Town, etc) for the images; Title, Caption, Category, WebSite Keywords and Publication Date for videos.

▪Products in the e-commerce shopping cart

The Search Engine extends its search to include all the products that have been added to the e-commerce shopping cart, analyzing the Name/Code and associated Description (see Product Settings | General).

▪Blog

All the pages in your Blog are included in a search. The Search Engine analyzes the Title, Author, Category, Tag, Caption andContent of each Post.

▪Members' Area

The pages with login and password access (inside a Members' Area) are not considered by the Search Engine, unless the user has already logged in.

▪Hidden pages

Pages that are Hidden in the navigation menu are treated as normal pages for the purpose of the search.

▪To exclude a page from the search

If you want to exclude a page from a search, select it from the Map, open the Page Properties window and, in the Expert section, deselect the Add this page to the Sitemap option.

▪Uppercase/Lowercase

The Search Engine is not case-sensitive: it does not differentiate between upper and lowercase letters.

The various parameters that the Search Engine considers have different relevance: for example, the occurrences of elements in page titles are considered very relevant. Thus, the occurrences of some parameters are automatically multiplied by a correction factor before being associated with other occurrences. Depending on the number of occurrences, a element's relevance is calculated and it is positioned accordingly in the Search Results page.
