Doesn't require * on search

[TiagoCavalcante]

Is your feature request related to a problem? Please describe.

I believe that the current way that searching works (that is, a result is only shown if there is an exact match, or if there is an * at the end of the search) could be improved just by not requiring a * at the end of the search pattern to show inexact matches.

This is the way Mathics works.

Describe alternatives you've considered

I believe that in the future it would be a good addition to have a similarity (or even more ideally, vector) search, as well as showing a part of the description of the results in the searches and adding an "other results" section with functions whose description contains the search.
