Feature: search also title, description and URL by default

[webysther]

The code looks like support this already but don't work:

opengist/internal/db/gist.go

Line 147 in 4b039b0

Where("gists.title like ? or gists.description like ?", "%"+query+"%", "%"+query+"%").

EDIT: Now I get how works, only search by content and is necessary to add the column name, any chance to search all fields always and only be specific if needed like gitea? Or be a option in the configuration to allow search all columns for who are interested.
