I have a lot of custom attributes set to be searchable, yet their prodcuts are not found by fulltext search. If I enable show in advanced search, at least their values start to show up in the product index table, but still they are not found.
For example i have a multiselect called model. There are twenty products with model “conic” - when I search for conic there are no results although they now appear in catalog_product_index_eav.
(Just to ask the most stupid question in the world)
Have you made a reindex?
bin/magento indexer:reindex
Yes, of corse, several times. If something is not working I do it all: setup update, indexer, di:compile - just do be sure.
