Hi,

I am a newbie to elasticsearch. Does anyone know any reasons for this  
exception while indexing data.

_"Caused by: java.lang.StringIndexOutOfBoundsException: String index out of  
range: -1_

   at java.lang.String.substring(String.java:1937)*

Hi,

Looks like formatting of the mapping settings. Would be helpful if you also paste the settings.

Cheers,  
Uri

ABC,

Check config/mappings/\_default and config/mappings/_YOUR-INDEX-NAME_directories, if you see any files there without an extension - rename them  
to have an extension (.json, for example).
