2)$\nSYM theory on any curved manifold can be enhanced at least to two by\nintroducing an appropriate $U(1)$ gauge background associated with the\n$U(1)_{
V
}$ symmetry. We then show that the generalized Sugino model on the\ndiscretized curved space,
which was proposed in our previous work,
can be\nidentified to the discretization of this SUSY enhanced theory,
where one of the\nsupersymmetries remains and the other is broken but restored in the continuum\nlimit. We find that the $U(1)_{
A
}$ anomaly exists also in the discretized\ntheory as a result of an unbalance of the number of the fermions proportional\nto the Euler characteristics of the polyhedra. We then study this model by\nusing the numerical Monte-Carlo simulation. We propose a novel phase-quench\nmethod called \"anomaly-phase-quenched approximation\" with respect to the\n$U(1)_A$ anomaly. We numerically show that the Ward-Takahashi (WT) identity\nassociated with the remaining supersymmetry is realized by adopting this\napproximation. We figure out the relation between the sign (phase) problem and\npseudo-zero-modes of the Dirac operator. We also show that the divergent\nbehavior of the scalar one-point function gets milder as the genus of the\nbackground increases. These are the first numerical observations for the\nsupersymmetric lattice model on the curved space with generic topologies.",

I need to look for all records that have created in a given range.
I tried:
GET _search
{
"query": {
"range" : {
"created" : {
"gte": "2012-01-01",
"lte": "2018-01-01",
"format": "yyyy-MM-dd"
}
}
}
}
I got:
{
"took" : 6,
"timed_out" : false,
"_shards" : {
"total" : 13,
"successful" : 13,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : null,
"hits" : [ ]
}
}
I expected a couple of hits for that query. I have verified that there are nearly 500 documents in my ES index.
What am I doing wrong here?
