QUESTION
Let's consider a list:
...ANSWER

- If I provide a space(anywhere in text field) it loads everything.
I don't observe that when trying your code. It will happen if your search string contains multiple consecutive spaces because String.split unfortunately does not collapse consecutive instances of the search pattern. For example, 'fooxxxbar'.split('x') will return ['foo', '', '', 'bar']. You later check if any of the tokens from recipeNamesList start with any of those elements, but ''.startsWith(string) is always true.
An easy way to fix that is to essentially collapse whitespace yourself by making the search pattern match one-or-more whitespace characters. That is, replace string.split(' ') with string.split(RegExp(r'\s+')).
Another easy way to fix it is to just continue if encountering an empty token to ignore it.
- If I type Bengali Curry it returns both Bengali Lamb Curry & 'Chingri Malai Curry'.
Your current algorithm always adds the results list whenever it finds any match. It searches for 'bengali', finds one item, adds it to results, searches for 'curry', finds both of those results, and adds both of them.
Instead of iterating over search tokens in the outer loop and iterating over the recipeNamesList tokens in the inner loop, it would make more sense to iterate over recipeNamesList, and on each iteration, check if all of the search tokens match the tokens of the search string. If so, then add that recipe name to the list of results1. That also would prevent the same recipe name from being added multiple times without needing to use a Set.
1 Or if you want fuzzier matching, record a score for each recipe name (e.g. the number of search tokens that were matched), sort the results by the scores, and discard any below a certain threshold.

QUESTION
I'm trying to implement trie search in flutter. And here's the entire trie.dart file.
The idea is something like this, say we have I have a list of recipe names:
...ANSWER
Answered 2021-Jun-04 at 19:34First, your TrieNode is using a List, which means you have to do a for-loop O(N) search for each char. It would be faster to use a Map.
(You could also use a 26D array, instead of a map, if you know that you'll only have English letters: [0] = 'A', [1] = 'B', ... [25] = 'Z')
Now I need to search using prefix so if the user searches for bur it'll show Burger. But if someone write Garlic Butter I need to Garlic Parmesan Butter. So, basically if the search query has multiple words I need to show the correct name.
bur is easy to do, as that's what a Trie data structure is for, but the garlic butter one is harder. You probably want to look into how to implement a fuzzy search or "did you mean...?" type algorithm:
However, maybe this is more complex than you want.
Here are some alternatives I thought of:
Option #1Change your TrieNode to store a String variable stating the "standard" word. So the final TrieNode of garlic parmesan butter and garlic butter would both have an instance variable that stores garlic butter (the main standard/common word you want to use).
Your TrieNode would be like this:

QUESTION
maybe a really stupid question here and I'm guessing this is actually nothing like as complicated as I'm finding it. However, after spending hours and hours reading and trying, while I've learnt a lot about Terraform, I'm really no closer to a solution which I can understand or reuse.
I'm trying to do something that would be pretty simple in bash or python but seems to require some trickery in Terraform. I have two variables that I want to "combine" so that I have a valid block of data usable in for_each looping for resource creation. It's quite likely that I have failed to do this properly from the beginning in terms of variable declaration. So please forgive my beginner invompetence.
Just to note also, this is mostly for my own learning so not necessarily a practical example bur rather a use case that illustrates what I want to understand better. In this context, my use case is to provision workspaces in Terraform cloud and to insert the same set of private variables in to each workspace created. aka create workspaces and push in azure service principle authentication variables.
So in variables.tf I have

QUESTION
I have a large table with a comments column (contains large strings of text) and a date column on which the comment was posted. I created a separate vector of keywords (we'll call this key) and I want to count how many matches there are for each day. This gets me close, however it counts matches across the entire dataset, where I need it broken down by each day. The code:
...ANSWER
Answered 2021-Apr-21 at 18:50As pointed out in the comments, you can use group_by from dplyr to accomplish this.
First, you can extract keywords for each comment/sentence. Then unnest so each keyword is in a separate row with a date.
Then, use group_by with both date and comment included (to get frequency for combination of date and keyword together). The use of summarise with n() will give number of mentions.
Here's a complete example:
