# Construct a narrow
|
|
|
|
A **narrow** is a set of filters for Zulip messages, that can be based
|
|
on many different factors (like sender, stream, topic, search
|
|
keywords, etc.). Narrows are used in various places in the the Zulip
|
|
API (most importantly, in the API for fetching messages).
|
|
|
|
It is simplest to explain the algorithm for encoding a search as a
|
|
narrow using a single example. Consider the following search query
|
|
(written as it would be entered in the Zulip webapp's search box). It
|
|
filters for messages sent on stream `announce`, not sent by
|
|
`iago@zulip.com`, and containing the phrase `cool sunglasses`:
|
|
|
|
```
|
|
stream:announce -sender:iago@zulip.com cool sunglasses
|
|
```
|
|
|
|
This query would be JSON-encoded for use in the Zulip API using JSON
|
|
as a list of simple objects, as follows:
|
|
|
|
```
|
|
[
|
|
{
|
|
"operator": "stream",
|
|
"operand": "announce"
|
|
},
|
|
{
|
|
"operator": "sender",
|
|
"operand": "iago@zulip.com",
|
|
"negated": true
|
|
},
|
|
{
|
|
"operator": "search",
|
|
"operand": "cool sunglasses"
|
|
}
|
|
]
|
|
```
|
|
|
|
The full set of search/narrowing options supported by the Zulip API is
|
|
documented in
|
|
[the Zulip Help Center article on search](/help/search-for-messages).
