Reason:

Elasticsearchrepository inheriting Springdata's Pagingandsortingrepository interface
So according to the JPA specification Findesblogbykeyword this method will find Esblog under the Keyword property ...
Change the method name to Finddistinctesblogbytitlecontainingorsummarycontainingorcontentcontaining.
