categories=[['animal','dog','cat','fish'],['positive','good','fine','great'],['negative','horrible',disgusting','awful'],['water recreation', 'relax','holidays','spa','beach','sea']]


def query_index():
    index = search.Index('products')
    for categ in categories:
        query_string = ' OR '.join(categ)
        results = index.search(query_string)
        if len(results)>0:
            print(categ[0])
            break

    for scored_document in results:
        print(scored_document)
