ok, So I figured this bit out with a few provisos........ ( there wasn't a
test that covered this case in the UnitTests)
Build the Search Requests like so :
{
search in "index/type" query
{
matchQuery("FIELD", field_value)
} scroll (KeepAlive - duration using ES duration syntax for eg: 1m -
indicating 1minute)
}.build
Once the query is built, the first query is executed like so :
client.execute(query)
The SearchResponse from the future returned, from executing the Query,
also returned a ScrollId
searchResponse.getScrollId
Subsequent Queries (to get scroll through the rest of the full results of
the query :
client.searchScroll(searchResponse.getScrollId,KeepAlive)
Keep in mind that the scrollId needs to be retrieved after each search
scroll call.
Even tho' there were two calls allowed for search scroll
client.searchScroll(scrollId) *and*
client.searchScroll(scrollId,KeepAlive)
Only the 2nd call actually worked in my case. the first call went thought
the first execution, and 2nd execution. But failed to return a scold on
the 2nd time around and so it failed to proceed beyond that point.
That said, if someone is able to point out why a KeepAlive parameter needs
to be passed (contrary to what ES' s site defines how scroll works)
Thanks
