Hey,
I am having a problem with the Lovely Systems plugin:
I have it compiled and installed, and it works fine when accessing it via
the REST API like so:
{
"query": {
"match_all" : {}
},
"facets" : {
"visits_histogram" : {
"distinct_date_histogram" : {
"field" : "timestamp",
"value_field" : "session_id",
"interval" : "day"
}
}
}
}
But if I try the same thing using the Java API:
elasticSearchService.client
.prepareSearch(indexes)
.setSearchType(SearchType.COUNT)
.setTypes('docHit')
.setQuery(QueryBuilders.matchAllQuery())
.setFacets([
visits_histogram: [
distinct_date_histogram: [
field: "timestamp",
value_field: "session_id",
interval: "day"
]
]
])
I get an error which I really can't figure out, also note that the above
code works fine for the regular date_histogram facet:
java.lang.NullPointerException
