Tag search problems

[HushedFox]

There are some problems with tag search

1. The text below results says that when searching for "wing" the results should be "winged humanization, wings, and spread wings" but this is not the case:

to get those result searching for "wing*" is needed, not "wing":

2. Another problem arises when searching for queries with spaces and wildcards, for example if I searchd for "*l wings*" I would expect to get "small wings", "artificial wings" and "mechanical wings" but instead there are no results.

This can be resolved by adding "name:" before the search query, but I think this should be always the default without the need to put that there.

3. When searching descriptions and using wildcards it doesn't work properly.

Another example: "one of the three" is a fragment of this tag's description:

but it can't be found:

and this is very strange behavior with the same description, let's try searching for the word "Caninae" (marked blue above):

it works, fine. But then the other word in italics from the same tag description, "Canidae" (marked green above):

It doesn't work...

There is still a problem with tag search, right now it just doesn't work at all for just wing:

but at least *l wings works now (there were no results earlier)

And it's the same on Derpibooru
