    So I found idea to fetch all data to my project and then search for the specified string and its key to find corresponding field with the same key value using this function:

    func searchAndUpdate(searchString: String) {
       let sevenDaysInSeconds: TimeInterval = 7 * 24 * 60 * 60
       let currentDate = Date()
       let sevenDaysAgo = currentDate.addingTimeInterval(-sevenDaysInSeconds)
       
       for (index, data) in info.enumerated() {
           for (key, value) in data.ExeName {
               if value == searchString {
                  
                   if let weightArray = data.weight[key], data.time > sevenDaysAgo.timeIntervalSince1970 {
                       let summary = Summary(Name: data.ExeName[key] ?? "",
                                             weig: weightArray,
                                             interval: data.time)
                       chartData.append(summary)
                       
                    
                    break
                   }
               }
           }
       }
   }

    The below is JavaScript(ish), but should be nearly identical in Swift:

    const valueToSearchFor = "Dumbbell Seated Scaption";

const myCollRef = collection(db, "some_collection");

const q = query(myCollRef,
                where("ExeName", "array-contains", valueToSearchFor),
                limit(1));

const querySnap = await getDocs(q);
const docSnap = querySnap.docs[0]; // pull out the first result
const theData = docSnap.data();

// find the position of `valueToSearchFor` in the "ExeName" field:
const position = theData.ExeName.indexOf(valueToSearchFor);

// get the "numberreps" array entry for corresponding `valueToSearchFor`
const numberRepsArray = theData.numberreps[position];

console.log("number of reps:", numberRepsArray);
