What is fuzziness?
As a search operator
In the main search bar, you can write a query with the search operator tilde (~) with a number, at the end of each word of your query. You can set fuzziness to 1 or 2. It corresponds to the maximum number of operations (insertions, deletions, substitutions and transpositions) on characters needed to make one term match the other.
kitten -> sitten (1 substitution (k turned into s) = fuzziness is 1)
kitten -> sittin (2 substitutions (k turned into s and e turned into i) = fuzziness is 2)
If you search for similar terms (to catch typos for example), use fuzziness. Use the tilde symbol at the end of the word to set the fuzziness to 1 or 2.
"The default edit distance is 2, but an edit distance of 1 should be sufficient to catch 80% of all human misspellings. It can be specified as: quikc~1" (source: Elastic).
Example: quikc~ brwn~ foks~ (as the default edit distance is 2, this query will catch all quick, quack, quock, uqikc, etc. as well as brown, folks, etc.)
Example: Datashare~1 (this query will catch Datasahre, Dqtashare, etc.)
In Batch searches
When you run a batch search, you can set the fuzziness to 0, 1 or 2. It is the same as explained above, it will apply to each word in a query and corresponds to the maximum number of operations (insertions, deletions, substitutions and transpositions) on characters needed to make one term match the other.
kitten -> sitten (1 substitution (k turned into s) = fuzziness is 1)
kitten -> sittin (2 substitutions (k turned into s and e turned into i) = fuzziness is 2)
If you search for similar terms (to catch typos for example), use fuzziness. Use the tilde symbol at the end of the word to set the fuzziness to 1 or 2.
