Many times, I know what I want to search for. For example the word "test" in a topic, or narrow a search with a word combination, where one or both are common, but together they are not.The following words in your search query were ignored because they are too common words: {word}.
You must specify at least one word to search for. Each word must consist of at least 3 characters and must not contain more than 14 characters excluding wildcards.
I suggest an option that says "Search anyway" after the warning. And don't automatically ignore the common word in a multi-word search.
Thanks
