Top Hits Aggregation Usage

[bertiepinnock]

Hi again,

When querying Elasticsearch with a Top Hits aggregation (using an aggregations data adapter), the plugin reads in the hits as a single field with a class type of org.elasticsearch.search.internal.InternalSearchHits. This prints out in the report as something like org.elasticsearch.search.internal.InternalSearchHits@524df193 rather than the actual contents of the hit.

Is there a way I'm missing to get the contents of the hit into the report?

Thanks very much!

Hi bertiep,

will look into it.

Hi bertiep,

I'm closing this issue. I have seen what the confusion may have been for you - it's a common mistake - and I decided to write a blog entry that explains what is happening and how to properly insert aggregation results into a report.

You can find the article here: http://blog.wedjaa.net/unrolling-es-results/.

Cheers,

Fabio

Thank you so much, that's fixed it!

Just a small thing, I think there's a typo in the blog post, I think the code snippet:
new net.sf.jasperreports.engine.JRBeanArrayDataSource($F{top_tag_hits Hits}.getHits())
Should be:
new net.sf.jasperreports.engine.data.JRBeanArrayDataSource($F{top_tag_hits Hits}.getHits())

Otherwise absolutely perfect, thank you very much again for the help!

Thanks for spotting the typo! Fixed it... it was a botched cut and paste.
