Fuzzy Lookup: A Powerful Query Tool in Azure Cognitive Search

When it comes to searching for specific terms or phrases in a database, accuracy is crucial. However, typos and misspellings can often occur, making it difficult to retrieve the desired results. This is where fuzzy lookup comes into play – a type of query that compensates for typos and misspelled terms in the input string.

In contrast with other queries that analyze text to handle different forms of the same word (e.g., 'mice' and 'mouse'), fuzzy queries take the text at face value without any linguistic analysis. The comparisons are based on the exact matches, without considering variations or permutations. Any documents that match on these exact terms are included in the results.

A graph is created for each term in the query, consisting of up to 50 expansions or permutations of each term. This captures both correct and incorrect variants, ensuring a comprehensive search. For example, if your query includes three terms 'university of washington', a graph is created for every term in the query, including stop words like 'of'.

When a fuzzy search is specified, the search engine builds a graph of similarly composed terms for all whole terms in the query. This query expansion exercise produces a match on terms having a similar composition, effectively auto-correcting typos when the discrepancy is just a few misplaced characters.

Azure Cognitive Search supports fuzzy search, making it an ideal tool for organizations that require high accuracy and precision in their search results. Whether you're searching for specific documents or looking to improve your search functionality, fuzzy lookup can help you achieve your goals with ease.
