Term breaks my field value into multiple values

hi all,
My field value looks like "UzC1qjJMt_afb-gjOewA:9". Term breaks it into three different values "UzC1qjJMt_afb", "gjOewA" and "9". It looks pretty consistent for all the field values. It sounds like an issue with term.

I am using elasticsearch 2.2.0

Can somebody confirm it? Thanks.

any help would be appreciated.

This would be the analysis that ES does during indexing time. You would need to set the field to not analysed in the mappings for the field.
