Quick Reference

Filter
Search for
syftenthe word "syften", "Syften" or "SYFTEN" (case insensitive).
google appleposts mentioning both of these companies.
"my podcast"the phrase "my podcast".
site:reddit.com/r/startups/posts on the /r/startups subreddit.
plug*"plugin", "plugins", "plug"... The star can only be placed at the end.
"good plug*"same as above, but for phrases.
beer NOT rootthe word "beer", but not if "root" is also mentioned.
title:domain title:nameposts with a title that includes both "domain" and "name".
title:"domain name*"posts with a title that includes the phrases "domain name", "domain names" etc.
`fmt.Printf("hi!")`this exact string, without ignoring special characters. These are backticks, not apostrophes.
author:user1 author:user2posts by user1 or user2.
replyto:someuserreplies to this user. Use in conjunction with site:. This doesn't work for all communities.
type:postposts, i.e. the items that create new threads.
type:commentcomments, i.e. replies to posts.
tag:sometagfor use with multiple email addresses and Slack channels.
// blah blah blaha comment.

The filter a.b.cwill match, among other things, the text "A... b!c". That's because special characters are ignored and word boundary logic is applied. This is what you would expect from a Google search.

However, Syften is not Google and does not need to instantly search thought terabytes of data. We're only filtering once, through live data, delivering the results and discarding the rest. This allows us some more CPU-heavy operations, like matching special characters. If you want to match special characters, like a text editor search would, surround your filter with backticks, like so: `a.b.c`.

Examples

Use Cases

Limit search to Slack communities only

Syften can search Reddit, Twitter, and many other leading communities. To limit a filter to Slack only specify site:slack.com:

site:slack.com yourwebsite.com

Limit search to just this one Slack community

You can narrow down your search to individual communities

site:techlondon.slack.com freelance

Channel tracking

We put the channel name in what is normally the post title for other backends:

title:`#marketing` "cold call"

Track users

Unfortunately we can't easily tell what the "Username" (e.g. reginald) of a Slack user is and the "Display Name" (e.g. Reginald Terris) is optional and can easily be changed.

So to make identifying users reliable we put the User ID (e.g. U57JWU42T) in the title field. Additionally, to make it convenient to view, we put the "Username" in the author field.

site:techlondon.slack.com title:U57JWU42T
site:techlondon.slack.com author:reginald

Track replies to your messages

To track replies to your threads track your own Slack user. Keep in mind that the User ID will, and the Username may be different in every Slack community.

site:techlondon.slack.com title:U57JWU42T

Learn from the best

See how the best do their marketing and learn from them. To avoid tracking their username across the different communities you can just follow urls to their websites.

site:slack.com marketingexamples.com
site:slack.com saasmarketer.io

Implementation Details

  • Alerts are available with an up to 1-minute delay.
  • Since Slack messages have no title, we're constructing a faux one that looks like this:
    message from someuser (U012ABCDEFG) in somecommunity.slack.com/#somechannel.
  • Item edits are tracked.
  • Thread replies are tracked.
  • The replyto: operator is not supported.
  • It's inconvenient to track a user across multiple Slack communities, as their username may be different.
  • The channel ID is included in the URL, and can be filtered with site: site:somecommunity.slack.com/archives/C12345678/

Twitter/X

Monitoring Twitter/X is completely separate from the other communities. We use the standard Twitter syntax, shown below. Syften does not support these operators: min_replies, min_faves, min_retweets.

Operator
Finds Tweets
watching nowcontaining both "watching" and "now". This is the default operator.
"happy hour"containing the exact phrase "happy hour".
love OR hatecontaining either "love" or "hate" (or both).
beer -rootcontaining "beer" but not "root".
#haikucontaining the hashtag "haiku".
from:NASAsent from Twitter account "NASA".
to:NASAreply to Twitter account "NASA".
@NASAmentioning Twitter account "NASA".
puppy -is:retweetcontaining "puppy", filtering out retweets.
puppy -is:replycontaining "puppy", filtering out replies.
puppy -is:quotecontaining "puppy" filtering out Quote Tweets.
has:links, has:hashtags, has:mentions, has:media, has:imagesself explanatory.
lang:enthis parameter restricts Tweets to the given language.
tag:yourtagthis is a special Syften-specific operator used to tag your filters.

Use Cases

Here is how I would search for relevant tweets in English about Syften that didn't come from me and didn't mention my Twitter/X handle:

syften -@syften_com -from:@syften_com lang:en
