Using rich text to more accurately, clearly and easily express a search term's intent

Many people overlook the ability for Google queries to exclude as well as include words or phrases - the syntax is ugly :

salsa recipe -tomatoes

Emphassist uses familiar typographical modifiers to make these more advanced searches easier, clearer and more natural :

salsa recipe tomatoes

Obviously it would be great if google supported more ways to modify and signal intent in your search queries. This is only made really as a simple proof of concept. Bold or underline to signal more important terms in a search query would be a lovely addition too ...
