Introduction

I previously wrote the following article, but GPT-4’s explanation was more useful, so I am sharing it here.

How to Implement Exact Non-Match Search in JavaScript

Fuse.js is a lightweight fuzzy search library that operates on the client side. However, it is not suitable for the purpose of exact non-match search. Instead, you can easily implement it using JavaScript’s Array methods.

Exact Non-Match Search Example

The following example uses the filter method to perform an exact non-match search.

c]cc)co;oo;on{}{}nn(ns,,ssisttctctttoioioeldtntnsrmealtltee).teeeeasla:n:n他ru=ottのcl>g=':':デht(EEーTsir[x'x'タeteaTaTr=esmhmhmmupipid.llsls=atteetisii'at)TsTsE.l;iixfetataailnlnml!eept=eele=1x2xer'a'a(s,m,mTeppialltreelcehccToo1enn'rtt;meenn&tt&ffiootrremtt.hhceeonfstieercnsottnd!i=ti=etmes.me'.a,'r,chTerm

In this example, elements from the data array that do not exactly match searchTerm are filtered. If both the title and content do not match searchTerm, the element is included in the result array.

In this way, exact non-match search can be implemented using JavaScript’s native Array methods.

Summary

Exact non-match search can be easily implemented using JavaScript’s Array methods. Fuse.js, being a fuzzy search library, is not suitable for implementing exact non-match search. Instead, a simple implementation is possible using the filter method.
