2. A system for processing a search request received from a user operating an input device, the search request directed at identifying a desired item from a set of items, each of the items having one or more associated terms, the system comprising: a first memory for storing at least a first portion of the set of items, and each item being associated with a set of terms to describe the item, each term being assigned a relevance value based on a relevance of an informational content of the term in identifying the associated item; a device input for receiving a query input from a user via the input device directed at identifying the desired item, the query input comprising two or more characters of two or more prefixes for terms the user is using to identify the desired item, the two or more characters including a first text portion and a second text portion, the second text portion being received subsequent to the first text portion; a processor for i) performing a first incremental find in response to receiving the first text portion and for ordering one or more items found in the first incremental find based on a first ranking order, the first incremental find comparing the user-entered prefixes with the terms associated with the items and ii) retrieving the relevance values for the user-entered prefixes matching terms associated with the one or more items found in the first incremental find, the first ranking order of the one or more items found in the first incremental find being based on the retrieved relevance values for the user-entered prefixes matching terms associated with the items, so that relatively more relevant items appear earlier in the first ranking order for user selection or activation, the processor also for i) performing a second incremental find in response to receiving the second text portion and for ordering one or more items found in the second incremental find based on a second ranking order, the second incremental find comparing the user-entered prefixes with the terms associated with the items and ii) retrieving the relevance values for the user-entered prefixes matching terms associated with the one or more items found in the second incremental find, the second ranking order of the one or more items found in the second incremental find being based on adjusted relevance values for the user-entered prefixes matching terms associated with the items, the relevance values of the terms associated with the items being adjusted in response to a count of the number of text characters received from the user, and an order of at least a portion of the one or more items found in both the first and second incremental finds being changed based on the adjusted relevance values of the terms; and a device output for transmitting at least one of the first and the second ordered one or more items to be displayed to the user, further comprising the terms associated with the items being organized into searchable subspace categories, each subspace category having a relevance bias value, wherein at least one of the first and second ordering the one or more items is further based on the relevance bias values of the subspace categories, wherein the relevance bias values are based on the count of the number of text characters received from the user.

The system of claim 2 , further comprising a display device for presenting the at least one of the first and the second ordered one or more items, the display device having display space allocated according to the subspace categories.
