I think most of your points are wrong. Quoted strings always work for me (symbols are still stripped -- Google is a natural language search engine, not a code search engine), and there is a &quot;not&quot; operator, if I understand what you mean by that. From the article you linked:<p>When you use a dash before a word or site,
it excludes sites with that info from your
results. This is useful for words with multiple
meanings, like Jaguar the car brand and jaguar
the animal.
Examples: jaguar speed -car or pandas -site:wikipedia.org
