Everybody has tried the simple search or how to make efficient search or having more control over the results from a search.
I used a package from pub.dev that could be helpful for many of you (i hope so).
I will leave a link with the package and i will explain how does it work and if someone wants to implement it in different ways, i will just post the way i'm using it if you have any other doubts or questions or need help you can contact me.
summary: two arguments, list of documents and word/term to search. It searches over the field you want it to search(within the document) and returns the documents that matched with the term.
Hope this helps someone!
