I have a site setup with a search box. The search looks in a channel field made with Grid. For some reason the results are not being displayed from the Grid, even though all other channels work as planned. Is this a bug in 2.7.2?
I've run into a very similar instance in which I didn't specify
search_in="entries" as a parameter so that the search runs into the entry fields rather than just the titles.
Without seeing your search form code, it is hard to say, but it sounds like this is your issue. If you are expecting to see results from content inside custom fields and aren't seeing it, try entering a search term for the title of your entry. If it yields results, change your search form to include the above parameter and try again. ;)
Per the docs:
search_in="entries", search_in="everywhere", search_in="titles" This parameter specifies which fields you would like to include in the searching. There are three possible values:
entries: The search will be conducted in the entry fields and titles of your channel. The associated comments will not be included.
everywhere: The search will be conducted in the title, entry fields, and in associated comments.
titles: The search will be conducted in the title of your entries. The channel entry fields and any associated comments will not be included. If this parameter is not set, the search will default to only search by “titles”.
