Cannot search static page


I added a search component on my site but I found that there were only cms contents in the search result. I tried to search static pages but nothing showed up.
I am sure I didn`t exclude those static pages from search results and I am having the CMS plan.

Any help please.

Here is my site Read-Only: LINK
(how to share your site Read-Only link)

OK… I think I figure out what is going on.
I turned the password protection on for my site and I guess the searching engine stopped index the static pages.
When I turn password protecion off and index my site manually, the search result is back to normal.
I hope my experience can help you if you are having the same issue.
