+Sometimes you may want to filter documents in Chroma based on multiple categories or tags e.g. `games` and `movies`.
 Unfortunately, Chroma does not yet support complex data-types like lists or sets so that one can use a single metadata
 field to store and filter by. It is also not possible to use fuzzy search `LIKE` queries on metadata fields.
 
 To solve this problem without introducing a complex logic on the client side, we suggest the following approach.
 
 When adding document to a collection add each category it belongs to as a boolean metadata field:
 
-!!! note "No Empty Categories"
+!!! note "No Empty Categories/Tags"
 
     Only add categories an item belongs to with flags set to `True`. 
     Do not add categories an item does not belong to and set the flag to `False`.
 
 ```python
-import uuid
 
-collection.add(ids=[f"{uuid.uuid4()}"], documents=["This is a document"], metadatas=[{"games": True, "movies": True}])
+collection.add(
+    ids=[f"{uuid.uuid4()}"],
+    documents=["This is a document"],
+    metadatas=[{"games": True, "movies": True}],
+)
 ```
 
 When querying documents, you can filter by multiple categories by using the `where` parameter:
 
 ```python
-results = collection.query(query_texts=["This is a query document"], where={"games": True, "movies": True})
+results = collection.query(
+    query_texts=["This is a query document"],
+    where={"games": True},
+)
+# or a more complex query
+results = collection.query(
+    query_texts=["This is a query document"],
+    where={"$or": [{"games": True}, {"movies": True}]},
+)
 ```
