在弹性搜索中搜索不同的日期格式

Question

I've indexed a date column from my mysql database with the following configuration

                    mappings:
                    first_name: { boost: 5 , type: string, index: not_analyzed }
                    last_name: { boost: 5, type: string, index: not_analyzed}
                    id:
                        type: integer
                    date_create:
                        type: date
                        format: YYYY-MM-dd'T'HH:mm:ssZ

How can I query elastic search using different date formats? eg any items that have 2015-10-01 as index should be searchable when I search for 'October 1' or 'Oct 1'

Is there a way to do it in elasticsearch or do I have to format the date before passing it to the finder?

You should use a tool to convert the user input into a full Date/DateTime/DateTimeOffset object.

In javascript Moment would be a great choice.

In C# DateTimeOffset.TryParse() is your friend.

Whatever language you're using I'm sure there is a built in date conversion library.
