Let me explain a scenario to better explain my question,
Assume I am working in a credit-card related company in which people uploads their receipts every month, I want to check if that person bought fruits or not. Let's assume we used OCR to extract only the names of items bought and stored in a list.
First thing I did is web scrape all the names of fruits found everywhere and I stored the names of each of them in a big text file.
Now I want to know how can I match/lookup and make a decision that person bought fruits.
1) Any search/match algorithms that works on huge amounts of data.
I'm just looking for advice on what to implement in this type of scenario. Thanks in advance.
