Problem with elasticsearch and wildcard character as keyword

    With enhanced search a strange thing happens: a search with a textual keyword and some other filter produces more results than a search with the wildcard character as keyword and the same filter.
    How is this possible? Is a bug or a misconfiguration of elasticsearch?
    Thanks

    Can you provide an example and can you reproduce it here? Have you enabled a stemming analyzer?

    Hi Mike,
    for example on this site a search for keyword "xenforo" in the subforum "Xenforo Suggestions" produces more results than a search with the wildcard character as keyword in the subforum "Xenforo Suggestions".
    search 1 (with keyword "xenforo"): 171 results http://xenforo.com/community/search/search/?keywords=xenforo&type=post&nodes[]=18
    search 2 (with keyword "*"): 100 results http://xenforo.com/community/search/search/?keywords=*&type=post&nodes[]=18

    In this case probably happens because are also displayed the posts in the search with a textual keyword, but my case is more complicated because doing the searching with wildcard, not find some results if I use in the filter a custom field of @Waindigo. Instead this does not happen in the standard search.

    I have enabled a stemming analyzer.

    Thanks Robust, but I would like to read the opinion of @Mike or another developer.

    "*" isn't a wildcard query on its own. It appears to actually be matching posts with a * in it. Searching without a keyword isn't expected, except in specific cases where it is allowed.
