The apparatus and methods disclosed herein implement a convenient and efficient web-browser based search-and-retrieve mechanism that incorporates a more responsive search engine coupled with an integrated collection display. The browser-based search-and-retrieve mechanism allows a user to quickly and easily retrieve a list of search items from a large database, select certain desired items, while continually having access to a visual interface displaying the collection of previously selected items. While viewing the collection of previously selected items, the search engine interface allows for the retrieval and selection of additional items from the database. In the most preferred embodiments of the present invention, the browser-based search-and-retrieve mechanism takes the form of a shopping cart with enhanced search capabilities for optimized online shopping websites. By utilizing a master index and one or more helper indices, the required search and retrieval time for selecting items from large databases can be minimized.
