There is currently no way to search for an identifier, e.g., a column name, without also matching text that contains that identifier. For example, if I want to search for a column called ExampleColumn but ignore ExampleColumn2, BadExampleColumn, etc., I could try the "Match whole words only" option. I want it to find all of these:

SELECT ExampleColumn FROM ExampleTable;
SELECT ExampleColumn, OtherColumn FROM ExampleTable;
SELECT [ExampleColumn] FROM ExampleTable;
SELECT et.ExampleColumn FROM ExampleTable et;
SELECT * FROM ExampleTable WHERE ExampleColumn=3;
SELECT SUM(ExampleColumn) FROM ExampleTable;

but only the first three are found. Without the whole words option, it would match all of the above, but would also match these:

SELECT NewExampleColumn FROM ExampleTable;
SELECT BadExampleColumn FROM ExampleTable;
SELECT ExampleColumn2 FROM ExampleTable;

Adding the ability to effectively search for identifiers, either as a new feature or by changing the definition of "whole word" to align with SQL identifiers, would make SQL Search much more useful, I think.
