QUESTION
I have realized that you cannot query for a "does-not-contain" array in Firestore which is very problematic. (I cannot query for that which a user has not seen, I am however wondering if you can compare collections and therefore highlight similarities)
Is there a way to make 2 queries to Firestore and afterward compare if similar fields exist within the collections?
For example, if I could make 2 queries to compare the collection "AllNews" with the collection "MyNews" and therefore be able to highlight "uid1" & "uid2" within a collectionviewcell since the items exist within both collections. This way a user can see all items within "AllNews" while at the same highlighting the ones he already has in his collection "MyNews".
...ANSWER
Answered 2022-Jan-23 at 10:16It will be very costly to compare the documents in a collection against the documents in another collection. Why? Because you need to read all the documents within both collections. It will be fine if your collections only hold a few documents but as the number of documents grows, this operation isn't feasible.
So to solve this, you should use an alternative solution, which will be to store only the UIDs in a document. You can either store them in an array or in a map. Then you only have to perform a single document read and compare the UIDs.
There is however a limitation, which is the maximum 1 MiB size of the document. If the arrays/maps for AllNews and MyNews don't fit into a single document then you should consider creating two documents, one for each category. If this isn't enough then you can create two or three documents for each category. In this way, you can reduce the number of reads consistently.
To make the comparison, please check the answer from the following post:
QUESTION
I've created a script to fetch different newspaper names derived from a search engine when I initiate search using different keywords, as in CMG제약,DB하이텍 e.t.c. in that pages top right search box.
I also used some customized dates within params to get results from those dates. The script is doing fine as long as I use a single keyword in the search list.
However, when I use multiple keyword in the search list the script only keeps up with the last keyword. This is the list of keywords I would like to use:
keywords = ['CMG제약','DB하이텍','ES큐브','EV첨단소재']
The script is short in size but because of the height of the params, it looks bigger.
I've tried so far with (works as intended as I used single search keyword in the list):
ANSWER
Answered 2021-May-24 at 10:48I believe the problem is that variable params is prematurely being overwritten with data for a subsequent request while a previous request is still being processed. params needs to be moved to fetch_content and not passed as an argument:
