The array contains will see whether that element exists in the array or not! Isn't there any way I can specify a particular index also?

Whats the best way to look up a document and find just one value in the array? So i have doc xyz and i want to find abc amidst an array of unique values.

This video is old but... How fast is this type of search?
Would it be faster to simply make a new binary field for each potential cart item?

Not Working where("row_id", "array-contains", row.row_id) my data row_id => { "0":"1" } not show any data

Hello! With this is it possible to reduce / optimize the counting of documents read?

Hi thank you so much for the video! please i would like to know if you could do some example for Ionic 4 + Firestore, im stucked at arrays on fields inside doc...

Can you query documents with array-contains that have an array of objects?

Quick videos are best for digesting info! Keep up the great content!

Hi, can you please explain what should i add in security rules.

is there a way to filter the document first?
eg: firestore.collection('carts).doc('cartA') then apply the where?
to check only if cartA has banana?

Great video! Thanks!! I see that you're comparing against a string. Is it possible to compare against an array of items? I Do you know why I can not use 'array-contains' more than once? When i run my code i have the following error: An error occured: Error: 3 INVALID_ARGUMENT:
A maximum of 1 'ARRAY_CONTAINS' filter is allowed. Thanks!!

This is very helpful! You should pursue this further.

Great content as usual. I just updated firebase so I can use this new feature. I don't take the time to read the changelog of everything I use. If you do, please make short videos on big new features. That'd be great :) Cheers

Is it possible to use this new feature for arrays of objects?

Great video. But how about not contain fields in array? Thanks!

Your videos are great, I'm learning a lot, I'm thankful to have the support of your videos!
Sometimes it is hard to understand or I can't understand at all, so If could do a video that is more like a step by step it would help a lot

Very nice, like all formats but this is perfect for a quick Github Gist...Looks like Firestore docs have not been updated yet either.

Yes. Quick videos.
