Using Fuzzy Search in Typesense Search Algorithm

TLDR Gilbert asked about fuzzy search in typesense. It was clarified by Kishore Nallan that a trie data structure and levenshtein distance are used in the process. Harrison also contributed to the conversation.

Hi, How fuzzy search works on the typesense search? I’ve read the article it uses damerau levenshtein distance, but I’ve check about the algorithm it just compare 2 strings and get the minimum distance between 2 strings. I’m curious how the algorithm works with the index data? I’m glad if u want to share, thanks.

We use a trie datastructure to store the words in the dataset. Then we compare the words in the query against trie and use that to get matching words.

Interesting, so do you guys use levenshtein distance distance at all? Or is that computed as you go down the trie?

Computed during trie traversal.
