/*
=	 Field must be equal to value supplied. 	               addQuery('priority', '=', 1);
>	 Field must be greater than value supplied	             addQuery('priority', '>', 1);
<	 Field must be less than value supplied.	               addQuery('priority', '<', 3);
>=	 Field must be equal or greater than value supplied    addQuery('priority', '>=', 1);
<=	 Field must be equal or less than value supplied       addQuery('priority', '<=', 3);
!=	 Field must not equal the value supplied.	             addQuery('priority', '!=', 1);



STARTSWITH  	 Field must start with the value supplied.   The example shown on the right will get all records where the short_description field starts with the text Error.	 
addQuery('short_description', 'STARTSWITH', 'Error');

CONTAINS	 Field must contain the value supplied somewhere in the text.  The example shown on the right will get all records where the short_description field contains the text Error anywhere in the field.	 
addQuery('short_description', 'CONTAINS', 'Error');

IN	 Takes a map of values that allows commas, and gathers a collection of records that meet some other requirement. Behaves as Select * from <table> where short_description IN ('Error'), which is identical to Select * from <table> where short_description='Error'. For example, to query all variable values that belong to a specific Activity, use the IN clause to query all Activities that are of that type, and store their sys_ids in a map, or comma-separated list. Then query the variable value table and supply this list of sys_ids.
addQuery('short_description', 'IN', 'Error,Success,Failure');

ENDSWITH	 Field must terminate with the value supplied.  The example shown on the right will get all records where the short_description field ends with text Error.
addQuery('short_description', 'ENDSWITH', 'Error');

DOES NOT CONTAIN	 Field must not have with the value supplied anywhere in the text.  The example shown on the right will get all records where the short_description field does not have the word Error.
addQuery('short_description', 'DOES NOT CONTAIN', 'Error');

NOT IN	 Takes a map of values that allows commas, and gathers a collection of records that meet some other requirement. Behaves as: Select * from <table> where short_description NOT IN ('Error').	 
addQuery('short_description', 'NOT IN', 'Error,Success,Failure');

INSTANCEOF	 Special operator that allows you to retrieve only records of a specified "class" for tables which are extended.  For example when going after configuration items (cmdb_ci table) you many want to retrieve all configuration items that are have are classified as computers.  The code to the right will do that.	
addQuery('sys_class_name', 'INSTANCEOF', 'cmdb_ci_computer');
