Hi,

I have introduced a default-mapping.json to store all fields of type  
string in a normal and a reversed version. That works great so far!

My problem is that now I cannot search for date fields anymore. It  
seems that the dynamic  
template applies to date fields as well, although I've  
set "match\_mapping\_type" to "string".  
Elasticsearch says: Field [...] is not a numeric type.

A possible solution would be to use field prefixes and configure  
the dynamic template to only apply to fields that match "string\_\*".  
e.g. document.string\_name, document.string\_email, document.date\_lastlogin,  
...

But I am not sure if this is the best solution.

Any hints greatly appreciated.

Heya,

This has been fixed in 0.18 branch and upcoming 0.18.3 (which will be out  
this week).

Hi Shay,

I just tested with the latest repository version 0.19.0 SNAPSHOT which  
includes commit:

\*Mapping: Improve applying guessed types on dynamic templates, closes #1446.  
\*  
But the problem still exists.

If I don't use this dynamic\_template I am able to search for strings and  
dates.  
If I use the given dynamic mapping above, then i can only search for  
strings but for dates it says: Field [...] is not a numeric type.

If you need more information about this or maybe some logs, please let me  
know.

Regards,  
Daniel

Hi Shay,

my mistake.

I've tested with the actual 0.19.0 SNAPSHOT and everything works as  
expected!
