I have a list that I am loading lazily - only 10 items at a time. When the user scrolls to the bottom another 10 are loaded etc. However I also want to have an option of searching for an item within the full list - not the lazy list. My list exists on client side but is 900+ items and rendering takes long. How can i keep my list displayed lazily but have the search box filter items from my full list.
*I am hoping that creating my on custom search with ng-change() is not my only option
Here is a small plnkr. The letters list is my full list that i want to be searchable. And the cachedLetters is what is rendered in the list
