# 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 web app'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:
|
|
|
|
```json
|
|
[
|
|
{
|
|
"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). There are a few additional
|
|
options, new in Zulip 2.1, that we don't document there because they
|
|
are primarily useful to API clients:
|
|
|
|
* `sender:1234`: Search messages sent by user ID `1234`.
|
|
* `stream:1234`: Search messages sent to the stream with ID `1234`.
|
|
* `pm-with:1234`: Search the private message conversation between
|
|
you and user ID `1234`.
|
|
* `pm-with:1234,5678`: Search the private message conversation between
|
|
you, user ID `1234`, and user ID `5678`.
|
|
* `group-pm-with:1234`: Search all (group) private messages that
|
|
include user ID `1234`.
|
|
* `pm-with:1234,5678`: Search all (group) private messages that
|
|
include user ID `1234` and user ID `5678`.
|
|
|
|
The operands for these search options must be encoded either as an
|
|
integer ID or a JSON list of integer IDs. For example, to query
|
|
messages sent by a user 1234 to a PM thread with yourself, user 1234,
|
|
and user 5678, the correct JSON-encoded query is:
|
|
|
|
```json
|
|
[
|
|
{
|
|
"operator": "pm-with",
|
|
"operand": [1234, 5678]
|
|
},
|
|
{
|
|
"operator": "sender",
|
|
"operand": 1234
|
|
}
|
|
]
|
|
```
