Indica supports fuzzy searches that enable you to search for terms that are similar to the term you define. To do a fuzzy search use the tilde, "~", symbol at the end of a Single word Term. For example to search for a term similar in spelling to "roam" use the fuzzy search:
roam~
This search will find terms like foam and roams.
Additionally, an (optional) parameter can be specified to define how similar the resulting terms should be. This similarity value is between 0 and 1, with a value closer to 1 only terms with a higher similarity will be matched. For example:
roam~0.8
The default that is used if the parameter is not provided is 0.5.
