    General:

    There is a limitation on the number of truncated search terms combined with the Boolean operator 'OR'.

    Example:

    Search query Search hits
    segregation OR isolation 87,295
    segregat* 29,424
    segregat* OR isolat* 187,609
    segregat* OR isolat* OR supermax* 187,733
    segregat* OR isolat* OR supermax* OR violen* 248,824
    segregat* OR isolat* OR supermax* OR violen* OR effect* 342,675
    segregat* OR isolat* OR supermax* OR violen* OR effect* OR organ* 397,276
    segregat* OR isolat* OR supermax* OR violen* OR effect* OR organ* OR media* 456, 826
    segregat* OR isolat* OR supermax* OR violen* OR effect* OR organ* OR media* OR influe* No Results found

     

    Details:

    The maximum allowed truncated search terms combined with the Boolean operator 'OR' are:

    • 7 terms with asterisk and the word length is greater than 2 (such as abb* or ab*c)
    • 3 terms with asterisk and the word length is less than 3
    • 8 terms with question marks
