in dbvizualizer (another DB query tool).. there is very good feature, that you can search the whole resultset by simply typing in a text box that appears on top of the resultset. In this way it was searching in all cells and all rows that has been fetched **"already"** i.e the search was not going to database to fetch the result, but it was doing in-memory search for the result that is already fetched (no new row fetching during this searching process)

For Example:
My result-set fetch size is set to 10,000 rows. now if i start typing in the search text box, then it will search in those 10,000 rows only.
Now i hv cleared the search and scroll to the bottom to fetch more rows lets say 1,000 more rows. Now if i search, then it should search in 11,000 rows.

Another Example:
My result-set fetch size is set to 10,000 rows. now if i start typing in the search text box, then it will search in those 10,000 rows only.
I have not cleared the searched box this time...
Now i scroll to the bottom to fetch more rows lets say 1,000 more rows. now after 1,000 rows has been fetched then the "search text" should be applied automatically to filter the result (in-memory).

This is very handy feature and you dont have to write complex SQL expression to write to search....
