How to parse list <object> sent from lightning component?

Hi All,

I am working on building a search component with filters which are passed by end users. Although i am able to capture the filters and send them to my apex class, I am not able to convert the list<object> to json or a wrapper in order to build my query.I have also given the input data formats that i receive in the code below. Can some one let me know as to how i can convert the list<object> to list<string> or list<wrapper> ?

// json sent by lightning component

//How the json gets converted and looks in debug logs currently

public class SearchFilterController {
    public static void saveAccountList(List<Account> accList) 
        Insert accList;
    public static void generateQuery(List<object> prodWrapList)

        system.debug('prodWrapList size >>>> '+prodWrapList.size());
        list<String> queryParams=(list<String>)prodWrapList;
        List<productWrapper> lstWrapper = new List<productWrapper>();
        //JSON.deserializeUntyped((list<string>)prodWrapList); ---->FATAL_ERROR System.TypeException: Invalid conversion from runtime type List<ANY> to List<String>
        //JSON.deserialize(prodWrapList, lstWrapper); ----> doesn't work
        system.debug('deserialized lst >>>> '+lstWrapper);
        public class productWrapper{
            public String searchStr{get; set;}
            public Map<String,String> fieldNames{get; set;}
            public list<String> criteriaType{get; set;}
            public productWrapper(){
                criteriaType= new list<String>();
                criteriaType.add('equal to');
                criteriaType.add('greater than or equal to');

                criteriaType.add('lesser than');

                for (String fieldName: schemaFieldMap.keySet()) {
                    try { 
                        fieldNames.put(fieldName, fieldName); 
                    catch(Exception e){
