If only part of a space group symbol is typed in, the search will find all space groups beginning with the specified string of characters, e.g. P21/ would find all of P21/m, P21/a, P21/c, etc.
However, P21, being a valid symbol in its own right, would find only this particular space group.
To find structures in either of, e.g., P21 and P21/m, create and store two separate queries, one for Space Group = P21 and one for Space Group = P21/m, and combine them (see Complex Query Combinations).
