# Semantic Router Filter
%% Cell type:markdown id: tags:
The Semantic Router library can be used as a super fast route making layer on top of LLMs. That means rather than waiting on a slow agent to decide what to do, we can use the magic of semantic vector space to make routes. Cutting route making time down from seconds to milliseconds.
%% Cell type:markdown id: tags:
## Getting Started
%% Cell type:markdown id: tags:
We start by installing the library:
%% Cell type:code id: tags:
``` python
!pipinstall-qUsemantic-router==0.0.29
```
%% Cell type:markdown id: tags:
We start by defining a dictionary mapping routes to example phrases that should trigger those routes.
%% Cell type:code id: tags:
``` python
fromsemantic_routerimportRoute
politics=Route(
name="politics",
utterances=[
"isn't politics the best thing ever",
"why don't you tell me about your political opinions",
"don't you just love the president",
"don't you just hate the president",
"they're going to destroy this country!",
"they will save the country!",
],
)
```
%% Output
/Users/zahidsyed/anaconda3/envs/semantic_router/lib/python3.11/site-packages/tqdm/auto.py:21: TqdmWarning: IProgress not found. Please update jupyter and ipywidgets. See https://ipywidgets.readthedocs.io/en/stable/user_install.html
# os.environ["OPENAI_API_KEY"] = os.getenv("OPENAI_API_KEY") or getpass(
# "Enter OpenAI API Key: "
# )
encoder=CohereEncoder()
# encoder = OpenAIEncoder()
```

Now we define the `RouteLayer`. When called, the route layer will consume text (a query) and output the category (`Route`) it belongs to — to initialize a `RouteLayer` we need our `encoder` model and a list of `routes`.
%% Cell type:code id: tags:
``` python
fromsemantic_router.layerimportRouteLayer
rl=RouteLayer(encoder=encoder,routes=routes)
```
%% Output
[32m2024-03-28 14:24:37 INFO semantic_router.utils.logger local[0m
In this case, we return `None` because no matches were identified.

# Demonstrating the Filter Feature
Now, let's demonstrate the filter feature. We can specify a subset of routes to consider when making a classification. This can be useful if we want to restrict the scope of possible routes based on some context.
For example, let's say we only want to consider the "chitchat" route for a particular query:
%% Cell type:code id: tags:
``` python
rl("don't you love politics?",route_filter=["chitchat"])
Even though the query might be more related to the "politics" route, it will be classified as "chitchat" because we've restricted the routes to consider.
Similarly, we can restrict it to the "politics" route:
%% Cell type:code id: tags:
``` python
rl("how's the weather today?",route_filter=["politics"])
