Searching functionality for any field like google desktop

[kaznum]

Sometimes, people don't remember where a word was input.
Sanataro has some fields to input (ex. item_name, tags, account name, etc).
It could be better if there is comprehensive searching functionality.

[kaznum]

Implemented at 09b1d61 with SQL 'LIKE' but this searches only items.name fields.
It should be better that this functionality be more arbitrary so that it searches other attributes (such as tag, account name, etc)

To do this, more flexible search engines such as full-text searching are needed.
