What is a Fuzzy Search?

Fuzzy Search: Search engines have been accessed every day by billions of users, from basic queries to various purposes for research purposes. According to recent data, approximately 9 billion searches are done every day on Google alone. But have you ever noticed when you make a spelling mistake and there are some mistakes in the queries that were to be searched and the search engine gives us a prompted rectified form of the search bar? That is what fuzzy search does. Fuzzy search can use various algorithms and find strings that match the search pattern.

Fuzzy searches use a fuzzy algorithm to find the most relevant and appropriate search but, what is it used for? What are the benefits of it and how does it work? Let’s try to understand the concept of Fuzzy Search and understand its various aspects of it.

How does a Fuzzy Search Work?

A fuzzy search can be very similar to that of a spell-check or an error-rectifying program but also way more than just about that. Let’s take a quick example to better understand this concept which is let’s say you typed in “technology” in the Google search bar and hit enter. The very first line just below the search bar would say “Did you mean technology?”. This can be used as a prime example of fuzzy search however, the fuzzy search can be more than this. Continuing along the same example, it not only provides you with the various and numerous pages of the results for the direct keyword but also provides you with the results that the algorithm might find relevant and related to the search that you have been trying to gain knowledge about. This may include various types of technology, examples of technology, and search for various other aspects that are connected and relevant. It works on a 0 or 1 basis, it detects various variations that have been ranging between the spectrum and provides the result that is the matching to the matching threshold frequency.

There are basically three various string operations that are performed on a normal string which also work for fuzzy search algorithms, they are:

  • Insertion: Insert a letter or two or terms that have been missing from the keyword and form it as an actual search term.
  • Deletion: Deleting a letter or two or words that have been unnecessary and additionally added without actually providing any additional meaning to it.
  • Substitution: Substituting a term or two in order to make the search keywords more relevant and to help the algorithm better understand and catch the keyword into the algorithm and provide you with the most relevant and best results possible.

These are the various functions that are the primary basis of a searching term that can be caught on to the fuzzy algorithm and triggers the algorithm to work and perform the task that has been designated to it.

What are the benefits of Fuzzy Search? Why was it needed?

The primary and well to be honest only reason fuzzy search has been used is as we discussed throughout modifying and aligning the search keywords in such a way that it provides you with the most relevant results that you have been looking for.

The need for it occurred through various reasons, the prominent one being that when people searched certain keywords they weren’t able to sort out various pages that have been just related to the topic, and English is the language with two words having the same meaning sometimes. So based on the various context and related terms, it was really hard to search through the majority of the pages without actually finding the material that is required. Hence, to tackle this issue effectively and efficiently, the concept of fuzzy search came into existence to avoid such problems in the future and so far it has definitely been working well so far as the algorithm has an increased success rate in searching through various databases than any other algorithm.

Sum-Up – Fuzzy Search

As we have studied in detail Fuzzy Search and the various functionalities and purposes it serves, we can understand why it is so important and why it is emphasized for search engines to sort out various databases and be able to put out the most relevant results without having a whole lot of hassle. Hopefully, this helped in answering all of your questions regarding this and was educational in learning about the topic.
