MongoDB Regex $and $or Search Query - mongodb

Question

I am trying to construct a query that will accept multiple fields that can be searched over using regex for partial field matching that also has a hard constraint on other fields.
Example:
Collection: "Projects"
Required Information: { propertyId: "abc", clientId: "xyz" }
Fields to be Searched: name, serviceType.name, manager.name
Currently, I have a query like this, but if there are no results it returns all the results, which isn't helpful.
{
'$and': [
{ propertyId: '7sHGCHT4ns6z9j6BC' },
{ clientId: 'xyz' },
{ '$or':
[
{ name: /HVAC/gi },
{ 'serviceType.name': /HVAC/gi },
{ 'manager.name': /HVAC/gi }
]
}
]
}
If anyone has any insight into this it would be much appreciated.
Example Document:
{
_id: "abc",
propertyId: "7sHGCHT4ns6z9j6BC",
clientId: "xyz"
name: "16.000.001",
serviceType: {
_id: "asdf",
name: "HVAC"
},
manager: {
_id: "dfgh",
name: "Patrick Lewis",
}
}
The expected result is to only find documents where propertyId = 7sHGCHT4ns6z9j6BC AND one at least one of the following keys: name, serviceType.name, or manager.name match an inputted string, in this case, it's HVAC and if none of the regex fields match, then return nothing.
UPDATE
The issue was with MongoDB, after restarting it, everything worked.

Answer 1

Try following script:
db.collection.find({
$and:[
{propertyId:"7sHGCHT4ns6z9j6BC"},
{
$or:[
{name: /HVAC/i},
{"serviceType.name": /HVAC/i},
{"manager.name": /HVAC/i}
]
}]
})
Query above will return a document or documents if and only if propertyId matches and either of name, serviceType.name or manager.name matches desired regex.
