Add and refine search functions to an existing page that searches in our documents table

We need to add the following search functionality (all are added as "AND" to the MySQL query) 1) a textbox that is compared to the field "text" for match (allways wildcard). Located under the Tags fields. And has same size as them. 2) a button next to the "upload date" dropdown opens a div in which 2 calendars allow selecting exact date interval. No postback, only javascript. When dates are selected here the current dropdown is overridden. When the dropdown is used again, these two calendars are reset so the dropdown is used in the query. Jumping to dates far from the current must be more user friendly than only the standard .NET calendar control. 3) a dropdown that is populated from all "file_type"s existing on the table. when selected only docs of this type are returned by the search. 4) add a dropdown for selecting units for file size (upper and lower) - B, kB, MB, GB. Default kB. The "using NuQuMailerTest;" line just includes the database connection and the query function. You can define the query and test it on your side and we will make it work on our side.
