Hello everyone! I have been learning iOS programming for a while now, and even though I don't think I know near enough to make this kind of app, I would still like to draft the idea and see what I would have to look deeper into: So the general idea for this app, is for it to be a searchable database made of text documents. Say for example that my database was made of three essays I've written for school. If I then searched for a word (or number etc.) a function would compare the search-word with every word in every document and present the most relevant result. (If I search for the word 'apple', for instance, and it occurs three times in one document and two times in the other, I would want these documents to be displayed in descending order). I hope you understand what I mean. I'm certain I would have to look into databases and how they work on a phone, but I'm also a little concerned about what type of format the text documents would have to be in, so that the word-finding function could search through them. I might be completely out of line here, but in any case I'm looking for someone who can point me in the right direction. I hope you understand what I mean. Thanks in advance!
