I’m in the process of upgrading my site from v6 to v8. Everything seems to be working as expected, except for the search page. There are a number of sub-pages that are not being searched on the new site. For example, if you were to search the term ‘beetle’ on the old search page (godofinsects.com :: Search) you will see a number of results. But if you search the same term on the new site (https://upgrade.godofinsects.com/index.php/search) it does not show results from any of the sub-pages.
Have you run the search index jobs? Also go to those pages and check they have not been excluded from the search.
that was it! many thanks!
