For those who are having problems with pagination (on pages than the first where searched string become None, listing all the data) when creating some kind of search engine using this tutorial. It can be solved by:
Stop the video on 12:02

- Removing "<int:page>" and "defaults={"page": 1}" from routes, keeping only one route with name and methods only.
- Remove as well the parameter "page" from the "def index()".
- Insert right below "def index():", this line: "page = request.args.get('page', 1, type=int)".
- Insert right before "per_page=pages" on line 30 "page=page";
- On Jinja2 template, where there are two occurences of "page=page" insert as well tag=tag.

Now it should work.

HI,
Thanks for this nice example.
I learned from this tutorial and achieved the same application like yours.

I am getting one issue -
Pagination is working fine.
when we search for something it shows the correct number of records and page numbers, but when we click on any page number now that time it shows all data. and "search for" also disappear.
could you check please and guide me on this.
