Searching from my different database collections

I have many database collections and when I search something I want to find it from these collections.
Is there anything for this ?for example a script or a code
PS. I can not unite all of these database collections into one, because it has limit of 10000 rows.

Hi Rashad,

if you are storing items that are effectively of the same type (ex. all are blogs posts, product offerrings, game scores, etc.) and you want to access them using a single query, you should absolutely store them in a single collection.

The 10,000 row limit is a limitation of an importer and not of the database itself. So, you can split your CSV file in several documents, that have 10k or less rows and import them into the collection one by one.

I hope this helps, let me know.

Thanks very much , it realy helped me <3
