Hi Guys,
I was trying to better the filtering mechanism for my use case.
When i use the existing filters like FieldCacheTermsFilter, TermsFilter i
see that the first filtering take up enough time may be for building the
FieldCache. Subsequent filters are fast enough.
Currently, I am using CachingWrapperFilter over TermsFilter over String
Fields.
a) I want to reduce the FieldCache Building time or atleast first filters
time.
b) Instead can i build a filter over DocValues ?
I have tried few things:
1> I have SortedDocValueField like doc.add(new SortedDocValueField("ID",
new BytesRef("123"))) and created a
TermsFilter based on BytesRef List for this field. But this doesn't
work.
2> When i use the SortedDocValueField as group field for grouping it
works.
Are there any ways out or did i miss somethings ?
