When searching for a series of words (not in quotes) the search results can suggest a section that may not be relevant.

Example query: https://commons.wikimedia.org/w/index.php?title=Special:Search&profile=advanced&profile=advanced&search=You+seem+to+be+unaware+that%2C+IIRC%2C+there%27s+an+informed%2C+consensus+view&fulltext=Search&ns0=1&ns2=1&ns3=1&ns6=1&ns12=1&ns14=1&ns100=1&ns106=1&searchToken=6rnu2evqnqo35su6uey0ww4xm

Section linked in first result: https://commons.wikimedia.org/wiki/User_talk:Ellin_Beltz/Archive_3#Why_you_delete_my_files_that_I_translate_from_English_to_Khmer

Actual section where that series of words appears: https://commons.wikimedia.org/wiki/User_talk:Ellin_Beltz/Archive_3#Understanding_when_PD-.2AGov.2A_applies_-_e.g._to_unpaid_work._2

The (section: Section heading) suggestion in the first result is not a literal match. The search will highlight a section if one of the search terms is present in the section name. So the words "you", "that" and "to" are the first close-enough (as the search is not exact) results in a section heading, so it suggests that section. Which is wrong. :(

Putting your search in quotes changes to the results to be literal, and removes any section suggestion.
