Handling multiple search fields in cypher or py2neo

Question

Just getting started with cypher. Trying to understand best way to handle this case. I need to query database based on several search fields(not always present). Wondering what's the best way to handle it. For e.g I collect data from html post request

storeName = request.form['storeName']
storeCountry = request.form['storeCountry']       
storeState = request.form['storeState']       
storeCity = request.form['storeState']

I'm using flask framework, so defined this function with py2neo to handle search fields. Not sure if I got it right but if all fields are set correctly, hopefully, something like this should work fine

def get_search_results(skipNumber,limitNumber, storeName, storeCountry,storeState, storeCity):
        query = """
        MATCH (store:store) WHERE store.name = {storeName}
        MATCH (store:store)-[:IS_IN_COUNTRY]->(c:Country) WHERE c.name = {storeCountry}
        MATCH (store:store)-[:IS_IN_STATE]->(s:State) WHERE s.name = {storeState}
        MATCH (store:store)-[:IS_IN_CITY]->(ct:City) WHERE ct.name = {storeCity}

        RETURN user SKIP {skip} LIMIT {limit}
        """

        return graph.cypher.execute(query, skip=skipNumber, limit=limitNumber, storeName=storeName, storeCountry=storeCountry, storeState=storeState, storeCity=storeCity)

I would like to handle cases where users only submit one or two fields.
For e.g
1. if users only submit store name, then I should be able to return all the nodes with that store name.
2. If users only submit store name and country. Return all the stores nodes in that country
3. If users only submit store name, country and state. Return all the stores nodes in that country and state

Is it possible to write a generic cypher query to handle such scenarios i.e ignore cases where field is not set or is None or I need to write different queries to handle each case ?
