Reading
http://www.elasticsearch.org/blog/all-about-elasticsearch-filter-bitsets/
it looks like the bool filter is the way to go when using a certain
combination of filters.
But what if it's only one filter, which is cached, and presumably a
bitset filter?
I'm talking about the "MissingField" filter.
should this
{
"bool": {
"must": {
{ "missing": {"field": "out_of_stock", "existence": True}}
}
}
}
performs better than
{
"missing": {
"field": "out_of_stock",
"existence": True
}
}
I just got a bit confused with the blog post. I think they both should
perform the same.
