Hi!
No, it should show, unless the keyword logic is set to “OR with exact word matches” or “AND with exact word matches”. In that case “360” does not mach “360dialog” as a single word. Same might happen with fulltext search, as it usually ignores numbers. If the result does show up for “0dialog” or “60dialog” and the keyword logic is not set for exact word matches then most likely fulltext is being used.
Exact matches mean, that in case of multiple keywords they are treated as one word and there is no search query with them separately.
