How to fill out approximate string comparator search

To fill out an approximate string comparator search, follow these steps:

1. Collect the data you want to compare with the search string. This can include a list of names, addresses, or any other relevant information.
2. Use an approximate string comparison algorithm, such as the Levenshtein distance or the Jaro-Winkler distance, to compare the search string with each item in your data.
3. Determine a threshold for similarity. This threshold will be used to determine if a string is considered a match or not. For example, you may set a threshold of 0.8, meaning any match with a similarity score above 0.8 will be considered a valid match.
4. Iterate through each item in your data and compare it with the search string using the chosen algorithm. Calculate the similarity score for each comparison.
5. If the similarity score of a comparison exceeds the threshold, consider it a match and include it in your search results. Otherwise, exclude it from the results.
