Topic: Advanced search truncates (badly) Grid Refs finer than 100 m = hectare
The placeholder Help for the Grid Reference filter in Advanced search says 'Enter any grid reference e.g.SK5740' but it does not qualify this.
If a 10 m (8-figure) grid reference is entered it is truncated to 6-figure by removing the last two digits, without warning.
e.g. SZ18229383 becomes SZ182293 and then treated as a 100 m (6-figure) grid reference which does not even contain SZ18229383. If truncation is necessary because a 'grid_ref_10' index is unavailable then the Easting and Northing should be truncated separately to produce SZ182938.
