word "2014-09-15" . _allThe field is a full-text segment, so the analysis process converts the date to three words: "2014" , "09" and "15" . When we _all query in 2014 a field, it's a match to 12 tweets, because these tweets all contain words 2014 :GET /_search?q=2014 # 12 resultsWhen we query in a _all field 2014-09-15 , we first parse the query string, produce a query that matches either Word, 2014 or, 09 15 it still matches 12 tweets, because they all contain words 2014
