Description
When performing a find with two filters on the same indexed date field, a reverse sort on that same date field will cause an assertion:
Assertion failure fieldsToExplode >= 1 src/mongo/db/query/planner_analysis.cpp 132
|
Example:
db.Coll.ensureIndex({"SomeDate.423.X": 1})
|
db.Coll.find({
|
$or: [
|
{
|
"SomeDate.423.X": { $gte: new Date(1388534400000), $lt: new Date(1420070400000) }
|
},
|
{
|
"SomeDate.423.X": { $gte: new Date(1356998400000), $lt: new Date(1388534400000) }
|
}
|
]
|
}).sort({ "SomeDate.423.X": -1 })
