I have problem with search in Magento 126.96.36.199. It does not return any results (I do not receive errors, neither in logs, nor on site). I have tried solutions suggested in threads linked below question however nothing changed. I have clean install of Magento on server where everything normally works. We tried to reindex and do rollback on older versions of CatalogSearch (after each change reindex). Products are set to visible in both catalog and search. Caches are all off. Any ideas please?
