I can't figure out how to stop chrome from adding on words to things that i've typed before in the search bar. for example, i have searched for "navy beans nutritiondata.self" previously. Now whenever i start typing "navy bean"... it completes the thing I typed before, "navy beans nutritiondata.self", so I have to press back space in order to just search for "navy beans". I already turned off "use a prediction service to autocomplete text in the search bar, which was found under settings/advanced/privacy. Any help?
It's a common issue but the Chromium team has always refused to provide a way to disable the inline autocomplete “feature”:
"the code and UX complexity of this is nontrivial because inline autocompletion is the central design feature around which all other omnibox decisions are based." https://bugs.chromium.org/p/chromium/issues/detail?id=667922#c8
I encourage you to create a report at https://bugs.chromium.org/p/chromium/issues/list (click the "New Issue" button near the logo) to ask for that feature.
Maybe if enough people do that, they'll consider providing that option.
