multiple word search in flutter - algorithm

Question

Suppose I have a recipe called Garlic parmesan butter. I need to return an object when the appropriate name has been found.
Now in a simple ad-hoc solution I can search in the following way:
class SearchRecipe {
late RecipeModel recipe;
RecipeModel returnRecipe(String? suggestion) {
for (int i = 0; i < Store.instance.getAllRecipes().length; i++) {
if (suggestion == Store.instance.getAllRecipes()[i].recipeName) {
return Store.instance.getAllRecipes()[i];
}
}
return recipe;
}
}
But I need a simple way where if the user types in Garlic butter I need to return the object associated with the Garlic Paremesan butter.
How can I do it?
Edit: I should've clarified that I'm working with a List of objects. So the Store.instance.getAllRecipes() basically returns a List<RecipeModel>.
Update 1: This is what I've written:
class SearchRecipe {
//late RecipeModel recipe;
RecipeModel returnRecipe(String? suggestion) {
List<RecipeModel> results = [];
suggestion!.split(' ').forEach((s) {
results.addAll(Store.instance
.getAllRecipes()
.where((element) => element.recipeName!.contains(s)));
});
results = results.toSet().toList();
for (int i = 0; i < results.length; i++) {
return results[i];
}
return results[0];
}
}

Answer 1

String search = 'Garlic butter';
List<String> list = [
'Garlic Paremesan butter',
'Butter',
'Garlic',
'Butter Garlic',
'Paremesan',
'Stackoverflow'
];
List<String> results = [];
search.split(' ').forEach((s) {
results.addAll(list.where((element) => element.contains(s)));
});
// Avoid repeated values
results = results.toSet().toList();

Answer 2

Split the user input at spaces. Then you have a list. You can check the list and depending on your preference implement a variety of behaviors.
You can match if all words in the list are found. You can return if at least one of the words is matched.
You could give preference to more contained words or you could check the order of words.
In either case you would also not check for equality but use a function like includes / contains to check whether the searched word is part of the name.
(Checking the order could be done by remembering which words you already identified and only searching after the words that were found. In your example you would find ‘garlic’ and after that you would just look through ‘paremesan Butter’ and try to find ‘butter’)

Answer 3

first split the input text
var string = "Hello world!";
string.split(" ");
// ['Hello', 'world!'];
then iterate over each word in above array and check whether the above
Store.instance.getAllRecipes()[i].recipeName contains above word.
if(str.equalsIgnoreCase(str))
{
//remaining code
}
try contains method.
.contains()
