I’m relatively new to Redis, and is pretty neat until now - thanks!
As I have a search case, I’ve installed RediSearch, and I cannot find a clear response about the point where I need to find a field that is contained in a given string - a kind of reverse search.
I would appreciate it if someone could tell me if RediSearch supports this scenario.
Now I’m doing this:
... local cursor = "0" repeat local res, err = redis:scan(cursor, "match", "books:*", "count", 1000) if not res then ngx.log(ngx.ERR, "failed to hscan: ", err) break end local data cursor, data = unpack(res) if next(data) then -- test the book name key from the index that matches the search query for key , value in pairs(data) do -- check if the book name contains the search query if string.find(query, value, 1, true) then return true end ...
In Elasticsearch I think it is named Percolate query.
