Fuzzy match searches are best used to search for a term that is commonly misspelled or to search for a term along with any possible typos. Fuzzy matches increase the number of records returned by allowing flexibility in the spelling of the search term to capture additional records that may be relevant to a search term.
To form a fuzzy match query, enter the search term followed by a tilde and the number of edits allowed.
For example:
arrhythmia~1
Edits can include added letters, deleted letters, substituted letters, or transposed letters. In the above example, arrhythmia~1 will return the following results:
Example: arrhythmia~1
| Example Results | Edit Types | Explanation |
| arrythmia | deletion | Arrythmia is missing the first 'h' |
| arrhythmic | substitution | Arrhythmic changed the ending 'a' to 'c' |
| arrhythmiae | addition | Arrhythmiae added an 'e' to the end |
| arryhthmia | transposition | Arryhthmia swapped 'y' and 'h' |
The number of edits allowed, specified by the number following the tilde, can be the whole number 0, 1, or 2. Unlike proximity searches, which don't have a specified maximum number of allowed position changes, fuzzy matches have a maximum of 2 edits. Adding a number higher than 2 after the tilde will return the results for 2.
