Expand search lines for tag search

Current search display only allow max 100 items per page.  (and I have several hundreds !!! ) 

Problem when I try to search by TAG is that I have to repeat it for each page : 

Do a reset of the search , expland display, go to next page and search , repeating this at each page is a pain. 

Having the possibility to display ALL item in one page would be great  and would save a lot of time and nervosity !!! 

Thanks a lot for considering this
