Q: How can I best search the web for exact LaTeX commands (e.g., \show as opposed to show)?
It appears that Google will not allow us to escape the \ character. So, searches for \show are interpreted as show. Needless to say, results would be tremendously more helpful if the search were interpreted as the former. (note: "\show" doesn't help either)
Q: Has anyone had success searching LaTeX commands using other search engine? More generally, does anyone know of search engines that are particularly well-suited for searching non-standard characters?
Best Answer
Google code search will let you search by regular expression and, if you like, restrict your search to TeX/LaTeX source files only.
