TYPO3's Indexed Search uses operators (+, -, | -> AND, NOT, OR) as a feature for advanced searching. unfortunately there is no known way to disable this feature. Do have a clue to remove those operator statements in TYPO3?
As an example, if you try to search for "Kim Jong-un", the search result will display the following line: "Search for "Kim" and "Jong" but not "un". So if you have named an article or a page in typo3 "Kim Jong-un", you shall not find it through the search.
