Hi, I am trying to make filters to query with multiple operands using python v4 client. I am combining different filters to make a combined filter at runtime.

for single\_filter in filters:  
combined\_filters = combined\_filters & single\_filter if combined\_filters else single\_filter

I want to add more operands to the filter. Is there any efficient way to make the filters at runtime?

Hi @Jegadeesh !!

I have used this code sample for creating dynamic filters on coderun:

Let me know if this is something you are looking for:

```auto
filter_metal = True

filters = [
    Filter("question").like("*is*"),
    (Filter("count").greater_than(5) & Filter("count").less_than(10))
]

if filter_metal:
    filters.append(Filter("question").like("*metal*"))

combined_filter = reduce(lambda x, y: x & y, filters)

from weaviate.classes import Filter

jeopardy = client.collections.get("Question")
response = jeopardy.query.fetch_objects(
    filters=combined_filter,
    limit=3
)

```
