Noticed the code you use:
{% for blog in pagination %}
Tags: {{ blog.tags }}
{% endfor %} It is not a recommended way.
The correct way is you have to use a nested loop and the tag links should be presented something like:
tag1 tag2 ...
It is never a good idea to store all the tags in just one field and separated with comma or whatever:
Book1 | tag1, tag2, tag3,...
But it is recommended to do like this:
Book1 | tag1 Book2 | tag2 ...
Hope this helps.
