HI,

 In my case , there are about five thousand fields, Can ES support

this? How do the number of fields affect the speed of searching?

Thanks.

A search is independent from the number of fields as long as you do not
search over this number of fields.

You can create as much fields as your memory und resources will let you do
so.

Hi,

  Actually, search need go over all fields,  every field has special

definition, the number of fields is too big to remember,
I need search all fields for any keywords, return matched docs and field
name to request.

 Why so many fields, cause the data come from tables of database.

Client want a system to search any data conveniently.

 There are other problems like, search results from two tables need do

a join-like operation.

 These requirements exceed  ES capcacity, I am not sure.

Thanks.

Are you using the _all field in your mapping? I think that could work. That
will make all data searchable, without having to worry about particular
fields.

Logstash does this for an example.
