This is an option, but this doesn't include alternative names and spellings, and (as far as I am aware) this also omits results for plurals.

For example, I've recently been searching for information about various chemicals, including "methylthioethane". This is a chemical which can be spelled either with or without a space between "methyl" and "thio".

If I include a space the result automatically corrects to methylthio methane, which is a different chemical, if I put this in quotation marks or click the "limit results to..." button I lose all the results that don't put a space in, and if I type in methylthioethane as a single word it gives results for a ton of other completely different chemicals with similar groups (e.g. Bismethylthiomethane) without even giving me an option to limit results, and I don't gets results for the spelling with a space.

Thanks for this information, it's exactly what the devs are looking for from using the [] button. Please replicate your search, then paste your above comments in the Send Feedback form.

Indeed - having specific example queries really helps. Thank you, I'll forward the suggestion to the rest of the team.

Thank you both of you. The results appear to have been fixed already. [methyl thioethane] still automatically corrects to [methylthio methane], but putting the whole thing in quotation marks now gives results both with and without the space and gives fewer false positives. Clicking [limit results to...] or putting both words into quotation marks allows for searching for chemicals with both methyl and thioethane groups without limiting results to methylthioethane. [methylthioethane] still gives a few false positives, but they're now ranked lower, and the wrong words no longer appear in bold.

It's refreshing to see a search engine that cares about feedback and giving the best results it can :)
