While searching, filters on data, specifying where to search and where not to search, can be applied. These filtering options are for searching through specific datatypes, as well as a subset of objects inside the current object (ie. a subset of databases of current connection, as subset of tables in current database or a subset of columns in current table).
The current filter settings are displayed in the Data Search Tab. To change the filters click on the link 'click to change' and this dialog will open. Select what objects and datatypes to search and click OK.
A few points to note are
The filter setting for datatypes is persistent (both inside current session and across sessions).
To search on the BIT type you should preferably use the hexadecimal operator. In MySQL BITs are returned to the client in binary form and searching with plain text - and also not even strings composed of '0' and '1' - does not make much sense. However x'1' will find all instances of a BIT(1) containing "1" and a BIT(4) containing "0001" etc.
To search a particular value in a specific column in the table when viewed in grid mode, you can right click anywhere in that column. From the menu that opens, there is an option to filter the value or search for any value similar to or different from the current cell selected. This option can also be accessed from the funnel shaped icon in the bar as shown in the figure:
