I know no computer science so struggled to understand How can I search for a keyword with special characters in Google Search?, but am I right that the most popular search engines (Google, Yahoo, ...) ignore all punctuation except these ?
If so, then what can I do if I must include standard punctuation like comma, period, ...? For example, if I want to search for clauses that end with "any such" (so that "any such" must be followed by a punctuation to mark the end of a phrase), then
any such, or
any such. will fail.
