can anyone tell me how to find a particular string in a specific channel by its channel id?

[pure schooner]

Explain more. What is that string? Like a search function?

[amber birch]

you want to scan all messages in the channel?

[storm tendon]

yes i want to just find a text from a channel

[amber birch]

then you have to iterate over channel history

[pure schooner]

Or cache all the messages like a mad man

[storm tendon]

[amber birch]

impossible when the channel has 100k+ messages

[pure schooner]

By caching I mean saving all the msgs in a db

[amber birch]

well that's impractical for a one-time use

[pure schooner]

Or building a dictionary

[storm tendon]

i just want to find a text

that's all

[amber birch]

well it's not that easy to go via past messages

if you want to do it for new messages only

easy

if you want to do it for old messages

not so easy
