Searching through firebase data: iOS, Swift

I wanted to know if it's possible and how you can search through firebase. My app has a textfield where you can fill in some specifications that's get 'saved' in through an array.

for example:

var arrayOfSpecs = ["13'", "Black"]

Now I want to search with 2 segmented options:

• Search for the name of one of the Elektronics that has a spec of 13" or is black" (this elektronic device may have other specs; but has to include at least one of the given specs)

• Search for the name of one of the Elektronics that only has the specs I wrote, less specs are ok but no more specs than where the person searched for.

Example: Search for "black" "13inch"; the searchResults could include a MacBook with one spec: "black", but it could also include a MacBook Pro with 2 specs: "black" and "13inch", but it can not include a MacBook Air with specs: "Black", "13 inch", "Retina"

The searchResult would come in a tableview, or would store the correct names of the searchResults in array, which I would put in a UITableView

Below my database, I'll hope you understand what I'm looking for.

thanks

Change your JSON Structure to

            Electroniks:{
                  Macbook:{..,
                           Specification:{
                               13inch : true,
                               black : true 
                              },
                            ...
                        },
                   iPhone:{..,
                           Specification:{
                               13inch : true,
                               black : true,
                               camera : true 
                              },
                            ...
                        },
                   iPad:{..,
                           Specification:{
                               xinch : true,
                               red : true,
                               camera : true 
                              },
                            ...
                        }
            }

I don't think you can match two node queries at once , But what you can is, you can match one specification .queryEqualToValue at a time

So a workaround would be :- retrieve all the parentNodes which have one particular Specification and then iterate through those to match your other Specification

  let parentRef = FIRDatabase.database().reference().child("Elektronics")
parentRef.queryOrderedByChild("Specification/black").queryEqualToValue(true).observeSingleEventOfType(.Value, withBlock: {(snap) in

        if let dict = snap.value as? [String:AnyObject]{

        for each in dict{

            print(each.0) //Would retrieve you every product name with colour black in specification i.e Macbook and iPhone
            print((each.1["Specification"] as! NSDictionary).count)//Number of specification
            parentRef.child("each.0").child("Specification").child("13inch").observeSingleEventOfType(.Value, withBlock: {(snapshot) in

            if snapshot.exists(){

                   print(each.0) //You found your product's with exactly 13inch and black Specification.This is their name
                   }

              })

            }
        }else{

            print(snap.ref)

          }
        })
