Personally I am not quite sure about what the difference is between the options "Search for all terms or use query as entered" and "Search for any terms".
Do you think it'd be easy to combine those options and maybe as well have a single search field where you can switch the function to author search?So let's say that we are searching for dunkin donuts in the advanced search and let's compare it to its equivalent query in Google's search:
- Does "Search for all terms or use query as entered" mean that it is a combination of this+dunkin +donuts
and this"dunkin donuts"
? Because when you want all the terms to appear in Google's SERPs then you add a + before each word and when you're looking for exact matches you type a phrase in quotes.
- Does "Search for any terms" simply meandunkin donuts
?
In any case, I think it would be a good idea to have a small question mark icon or simply a link to point to a section in the FAQ that will have usage examples for all the search operators.
