Gmail’s Czech interface has “an interesting feature; when searching for words with a lot of inflectional forms, Gmail shows an option to check all the morphological variants. Gmail adds to the query "morph:on" and typically shows more results,” Jiri Z. spotted. Gmail is one of the Google services with a rudimentary search feature. Unlike Google Search or Google Docs, Gmail doesn't show spelling suggestions and it doesn't search for other forms of your keywords. If you search for "author", Gmail doesn't show messages that include the word "authors"; if you search for "web site", you won't find messages that only include "website". Note: this feature doesn’t work in English interface.
