有没有办法根据字符串相似性过滤django查询集(la python difflib)？

from difflib import get_close_matches
from django.db.models import Q
from .models import MyModel

def filter_queryset_by_similarity(queryset, search_term):
    # 获取所有字段名
    field_names = [field.name for field in MyModel._meta.fields]

    # 获取与搜索词相似的字段名
    similar_field_names = get_close_matches(search_term, field_names, n=3, cutoff=0.5)

    # 构建查询条件
    query_conditions = Q()
    for field_name in similar_field_names:
        query_conditions |= Q(**{field_name__icontains=search_term})

    # 过滤查询集
    filtered_queryset = queryset.filter(query_conditions)

    return filtered_queryset
