### fuzzySearch
|
|
|
|
Determines if the `patrn` matches with `str`
|
|
|
|
Loops through `str` and determines if it contains all characters of `patrn` and in the correct order. Both the strings are converted to lower case.

Taken from [here](https://github.com/forrestthewoods/lib_fts/blob/80f3f8c52db53428247e741b9efe2cde9667050c/code/fts_fuzzy_match.js#L18).
|
|
``` js
|
|
fuzzySearch = (patrn, str) => {
|
|
const pattern = patrn;
|
|
const string = str;
|
|
let patternIdx = 0;
|
|
let strIdx = 0;
|
|
let patternLength = pattern.length;
|
|
let strLength = string.length;
|
|
|
|
while (patternIdx !== patternLength && strIdx !== strLength) {
|
|
let patternChar = pattern[patternIdx].toLowerCase();
|
|
let strChar = string[strIdx].toLowerCase();
|
|
if (patternChar === strChar)
|
|
++patternIdx;
|
|
++strIdx;
|
|
}
|
|
|
|
return patternLength !== 0 && strLength !== 0 && patternIdx === patternLength ? true : false;
|
|
}
|
|
```

|

|
``` js
|
|
fuzzySearch('rt','Rohit'); // true
|
|
fuzzySearch('tr','Rohit'); // false
