Fuzzy Search Settings

Fuzzy Minimum Similarity

This sets the degree to which an incorrectly-spelled word will find what is required. Using the example of geological misspelled as geolgical, these might be the result of searches with a range of settings.

  • Fuzzy minimum similarity set to 50% - searching on geolgical finds all items with geological in the metadata.
  • Fuzzy minimum similarity set to 75% - searching on geolgical finds some items with geological in the metadata.
  • Fuzzy minimum similarity set to 95% - searching on geolgical finds no items with geological in the metadata.
  • Fuzzy minimum similarity set to Not fuzzy - searching on geolgical finds no items with geological in the metadata.

Fuzzy searching is inhibited by placing quotes around the search term.

You might like to try experimenting to find the best setting for you and your users, or otherwise a good starting point might the default as delivered value of 50%.

Fuzzy Prefix Length

The Fuzzy Prefix Length is the number of leading characters that must match the search term exactly before fuzziness is invoked. For example a setting of 5 would be needed to invoke fuzziness on the miss-spelling geolgical.

You might like to try experimenting to find the best setting for you and your users, or otherwise a good starting point might the default as delivered value of 5.

Maximum Suggestions Setting

If a search returns no results at all, suggested variations on the search term can be offered. The maximum number of suggestions that will be offered can be set between 0 and 5.
